15v dual typical application this series of converters does not require any external components for proper operation. however, if the distribution of the in put voltage to the converter contains significant induct ance, a capacitor across the input terminals may be required to stabilise the input voltage. a minimum of 1 f, quality electrolytic / ceramic capacitor is reco mmended for this purpose. for output decoupling it is recommended to connect, directly across the output pins, a 1 f ceramic capacitor (for 3.3 v and 5 v outputs) or a 0.27 f ceramic capacitor (for 12 v outputs). synchronization feature it is possible to synchronize the switching frequency of one or more converters to an external symmetrical clock signal. it is recommended that the signal be driven by a ttl compatible output. the rise time of the clock signal should be less than 10 ns. if the synchronization feature is not used, it should be left open circuit. turn-on input voltage an external resistor can program the input voltage at which the converter switches on. the voltage at which the unit switches off is typically 1 v below the turn-on input voltage (vion). the characteristic curves below shows the typical resistor values required to achieve adjustment of turn-on input voltage ( vion). to decrease vion the resistor should be connected between pins 10 and 11. to increase vion the resistor should be connected between pins 11 and 17. rnd0.8z hh - re s is t an ce r e q u ir e d t o decrease vion 0 500 1000 1500 2000 33.8 33.66 33.33 33 32 31 voltage (vion) kohm rnd0.8z hh - re s is t an ce r e q u ir e d t o increase vion 0 200 400 600 800 10 0 0 12 0 0 14 0 0 16 0 0 3 4.3 34 .8 3 5.2 3 7.5 4 0.5 4 2 voltage (vion) kohm rnd02zge - resistance required to decrease vion 0 200 400 600 800 10 0 0 12 0 0 14 0 0 16 0 0 35.6 3 5.4 35 3 4.2 33 .5 33 voltage (vion) kohm rnd02zge - resistance required to increase vion 0 200 400 600 800 1000 1200 1400 1600 36.05 36.45 36.9 37.5 39.5 42 voltage (vion) kohm may 09, 2006 revised to jun 29, 2006 page 11 of 16 www.power-one.com rnd dc-dc series data sheet 10w smt converter ? 15v dual output voltage trim note: for setting nominal output voltage pin 8 must be connected to pin 9. the trim feature allows the user to adjust the output voltage from the nominal. this can be used to accommodate a different requirement or to do production margin testing. output voltage can be adjusted by an external resistor. if pin 8 and pin 9 are not connected together the output will decrease to a low value. to increase vo a resistor should be connected between pin 8 / 9 and pin 17 ( -vin). to decrease vo, a resistor should be connected between pin 8 and 9 (nor). to increase vo: radj = a x (b - vd) / (vd - vo), k where: vd = desired output voltage vo = nominal output voltage. to reduce vo: radj = c x (vo - vd) / (vd - d), k where: vd = desired output voltage vo = nominal output voltage. model a b c d rnd02zge 0.5 3.92 2.0 2.56 rnd02zgg 0.5 7.1 2.243 3.7 rnd0.8zhh 0.572 16.126 2.243 8.295 notes: 1. when the output voltage is trimmed up, the output power from the converter must not exceed its maximum rating. this is determined by measuring the output voltage on the output pins, and multiplying it by the output current. 2. the trim feature allows the generation of additional standard voltages such as 15 v from the 12 v model. parallel operation paralleling of two converters is possible by direct connection of the output voltage terminal pins. the load regulation characteristic is designed to facilitate current sharing (typically 20%). output current limiting when the output is overloaded above the maximum output current rating, the voltage will start to reduce to maintain the output power to a safe level. in a condition of high overload or short-circuit where the output voltage is pulled below approximately 30% of vo.nom, the unit will enter a ?hiccup? mode of operation. under this condition the unit will attempt to restart, approximately every 100 ms until the overload has cleared. thermal considerations the converter is designed for natural or forced convection cooling. the output power of the converter is limited by the maximum case temperature (tc). to ensure reliable long term operation of the converters, and to comply with safety agency requirements, power-one limits maximum allowable case temperature (tc) to 110 c (see mechanical drawings). remote control feature the remote control pin functions as a normal soft shutdown. it is referenced to the ?vin pin. with positive logic, when the remote control pin is pulled low, the output is turned off and the unit goes into a very low input power mode. an open collector switch is recommended to control the voltage between the remote control pin and -vin pin of the converter. the remote control pin is pulled up internally, so no external voltage source is required. the user should avoid connecting a resistor between the remote control pin and the +vin pin. the user must take care to ensure that the pin reference for the control is connected close to -vin pin. the control signal must not be referenced ahead of emi filtering, or remotely from the unit. if the remote control pin is not used, it can be left floating. may 09, 2006 revised to jun 29, 2006 page 12 of 16 www.power-one.com rnd dc-dc series data sheet 10w smt converter ? 15v dual safety considerations these converters featur e 1500 vdc isolation from input to output. the input-to-output resistance is greater than 10m ? . these converters are provided with basic insulation between input and output circuits according to en60950 / ul1950 / csa60950-00. nevertheless, if the system using the converter needs to receive safety agency approval, certain rules must be followed in the design of the system. in particular, all of the creepage and clearance requirements of the end-use safety requirements must be observed. these documents include ul60950, csa60950-00 and en60950, although specific applications may have additional requirements. in order for the output of the converter to be considered as selv (safety extra low voltage) or tnv-1, according to en60950 / ul1950 / csa60950-00, one of the following requirements must be met in the system design: ? the converter has no internal fuse. an external fuse must be provided to protect the system from catastrophic failure. a fuse with a rating not greater than 2.0 a is recommended. the user can select a lower rating fuse based upon the inrush transient and the maximum input current of the converter, which occurs at the minimum input voltage. both input traces and the chassis ground trace (if applicable) must be capable of conducting a current of 1.5 times the value of the fuse without opening. the fuse must not be placed in the grounded input line, if any. ? if the voltage source feeding the module is selv, the output of the converter is considered selv and may be grounded or ungrounded. ? the circuitry on the converter carry transients, which exceed the input voltage. even if the input voltage is selv (<60v) the components on the primary side of the converter may have to be considered as hazardous. a safety interlock may be needed to prevent the user from accessing the converter while operational. emc specifications conducted noise: the converters meet the requirements of en55022, cispr22 and fcc cfr title 47 part 15 sub-part j - conducted (conducted noise on the input terminals) without any external components. the results for this solution are displayed below. to meet level b for the above standards it is necessary to fit a 3.3 f ceramic capacitor across the input terminals. electromagnetic susceptibility: standard applied stress class level performance outcome * electrostatic discharge en61000-4-2 2 kv to pins 1 b electromagnetic field en61000-4-3 3v/m 2 a electrical fast transient en61000-4-4 2000 vp to input 3 b conducted disturbances en61000-4-6 3vrms to input 2 b * a denotes normal operation, no deviation from specification. b denotes temporary deviation from specification is possible. conducted emi (input terminals) 0 10 20 30 40 50 60 70 80 1.e+05 1.e+06 1.e+07 1.e+08 freq (mhz ) dbv en55022 a a v. en55022 a qp . 0.1 1 10 30 may 09, 2006 revised to jun 29, 2006 page 13 of 16 www.power-one.com rnd dc-dc series data sheet 10w smt converter ? 15v dual surface mount assembly soldering: the following instructions must be observed when soldering the unit. failure to observe these instructions may result in failure or significant degradation of the module performance. power-one will not honor any warranty cl aims arising from failure to observe these instructions. this product is approved for forced convection reflow soldering only. the curves below define the maximum peak reflow temperature permissible measured on pins 1 and 10 of the converter. the lead-frame is constructed for a high temperature glass filled, ul94v0 flame retardant, diallyl ortho-phthalate moulding compound commonly used for packaging of electronics components. it has passed nasa outgassing tests and is certified to mil-m-14. the coefficient of thermal expansion is equivalent to fr4. the gull wing leads are formed to ensure optimal solder joint strength and structure. furthermore they facilitate visual inspection (manual or automatic). the leads are formed from a 97% cu alloy plated with cu and sn 90. this material is commonly used in the manufacture of integrated circuits. it has good corrosion resistance and exhibits the nobility inherent to all high copper alloys. unlike brasses, th is material is essentially immune to stress corrosion cracking. it also exhibits excellent solderability. it is readily wetted by solders and performs well in standard solderability tests. (dip of class ii or better). the product is manufactured with a patented process, which is fully automated, and ?in-line?. this ensures that there is no contamination or mechanical stress on the lead-frame so that the co planarity and solderability are maintained. the product is shipped in jedec trays to ensure preservation of the co-planarity and enable fully automated assembly in the final application. . pick & place assembly: the product is designed with a large flat area in the center of the top surface to serve as a pick up point for automated vacuum pick and place equipment. the ?open board? construction of the unit ensures that weight is kept to a minimum. however due to the relatively large size of the component, a large nozzle (> 8.0 mm, depending on vacuum pressure) is recommended for picking and placing. the unit may also be automatically handled using ?odd-form? placement equipment, with mechanical grippers. for this type of equipment the end edges of the device, which have no leads and also feature the greatest dimensional accuracy, should be used as pick-up points. restriction curve above 215oc peak temp. at pins 1 and 10 (oc) 200 205 210 215 220 225 230 235 240 245 10 20 30 40 50 60 tp (s) time (s) 0 50 100 150 200 250 300 0 40 80 120 160 200 240 280 320 360 400 440 max. temp. on pins 1 and 10 during reflow soldering (deg c) tp peak temperature (see fig below) 190 ? 450 s may 09, 2006 revised to jun 29, 2006 page 14 of 16 www.power-one.com rnd dc-dc series data sheet 10w smt converter ? 15v dual mechanical drawing note:- mm[inches] tolerances: - 0.5-10 0.1 10-100 0.2 may 09, 2006 revised to jun 29, 2006 page 15 of 16 www.power-one.com rnd dc-dc series data sheet 10w smt converter ? 15v dual 315 62.1 33.3 2 4 . 1 5 4 3 . 8 322.6 1 2 . 1 9 12.19 jedec tray may 09, 2006 revised to jun 29, 2006 page 16 of 16 www.power-one.com rnd dc-dc series data sheet 10w smt converter ? 15v dual pinout pin designation function reference 1 vout1 output voltage 1 (positive) secondary 2 rtn output voltage return secondary 3 vout2 output voltage 2 secondary 4 nc not connected secondary 5 nc not connected secondary 6 nc not connected primary 7 sync synchronization input primary 8 trim output voltage adjust note: - to set nominal output voltage connect pins 8 and 9 together primary 9 nor connection for nominal output voltage primary 10 toa turn-on/off input voltage adjust primary 11 rc remote control. pull low to turn unit off primary 12 nc not connected primary 13 nc not connected primary 14 nc not connected primary 15 nc not connected primary 16 nc not connected primary 17 -vin negative input voltage primary 18 +vin positive input voltage primary ordering information options suffixes to add to part number rohs lead-solder exempt compliant 1 no rohs suffix character required rohs compliant for all six substances add "g" as the last character of the part number. 1 the solder exemption refers to all the restricted materials except lead in solder. nuclear and medical applications - power-one products are not des igned, intended for use in, or authorized for use as critical components in life support systems, equipment used in hazardous env ironments, or nuclear control systems without the express wr itten consent of the respecti ve divisional president of power-one, inc. technical revisions - the appearance of products, including safe ty agency certifications pictured on labels, may change dependi ng on the date manufactured. specifications are subject to change without notice. |
