ims30 series: 30w dc- dc converters 32-75v input 3.3v & 5.1v, 1.8v & 3.3v dual outputs rev. jun 10, 2004 page 8 of 12 typical application this series of converters does not require any external components for proper operation. however, if the distribution of the input voltage to the converter contains significant inductance, a capacitor across the input terminals may be required to stabilise the input voltage. a minimum of 1f, quality electrolytic / ceramic capacitor is recommended for this purpose. for output decoupling it is recommended to connect, directly across the output pins, a 1f ceramic capacitor. remote control features:- x shutdown (positive logic) the remote control pin functions as a normal soft shutdown. it is referenced to the vi- 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 the vi- 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 vi+ pin. the user must take care to ensure that the pin reference for the control is connected close to the vi- 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. x inhibit (negative logic) ( option ?i? excludes shutdown) the output(s) of the converter may be enabled or disabled by means of a logic signal (ttl, cmos, etc.) applied to the inhibit (sd) pin. no output voltage overshoot will occur when the unit is turned on. if the inhibit function is not required the inhibit pin should be connected to vi- to enable the output (active low logic, fail safe). programmable undervoltage lockout the remote control pin (sd) can also be used as a programmable undervoltage lockout. the undervoltage lockout value is 30v with a typical 0.5v hysteresis window, which can be trimmed up by means of an external resistor, connected between the sd pin and vi- pin. 48ims30 rext [k : ] vi min [v] 31 50 34 29 36 20 38 15 40 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 100ms until the overload has cleared. synchronisation feature it is possible to synchronise the switching frequency of one or more converters to an external symmetrical clock signal. consult factory if this option is required, for full application details. short circuit behaviour the current limit characteristic shuts down the converter whenever a short circuit or an overload is applied to its output. the converter self-protects and automatically recovers after removal of the overload condition (hiccup mode).

ims30 series: 30w dc- dc converters 32-75v input 3.3v & 5.1v, 1.8v & 3.3v dual outputs rev. jun 10, 2004 page 10 of 12 safety considerations these converters feature 1500 volt dc isolation from input to output. the input to output resistance is greater than 10mohm. 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: x 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 3.15a 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. x if the voltage source feeding the module is selv, the output of the converter is considered selv and may be grounded or ungrounded. x the circuitry of the converter may generate 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: ims30 suggested circuit required for level b of cispr 22/en 55022, measured at u i nom and i o nom . reference designator description part number vendor tr01 80 p h common mode choke pd0034 pulse engineering c01 1 p f ceramic capacitor 18124c105kat4a a v x l01 47 p h inductor ds5022p-473 coilcraft c02 47 p f electrolytic capacitor b41588-d9476-t siemens c03 130nf ceramic capacitor 1206b134m101nt novacap electromagnetic susceptibility: standard applied stress class level performance outcome * electrostatic discharge en61000-4-2 2kv to pins 1b electromagnetic field en61000-4-3 3v/m 2 a electrical fast transient en61000-4-4 2000 vp to input 3b conducted disturbances en61000-4-6 3vrms to input 2b * a denotes normal operation, no deviation from specification. b denotes temporary deviation from specification is possible.
