single output uep models features ultra- high density, 2" x 1" 1.2-6 amp, 15-30 watt dc/dc's figure 1. simpli?ed schematic the uep series dc/dc converters deliver the most power/current (up to 30w/6amps) from a 1" x 2" package. and because of their footprint compatibility, they can be used as drop in replacements for their bigger brothers, the standard 2" x 2" and 1.6" x 2" devices, commonly used in the industry. by combining a high-frequency (340khz), high-ef?ciency (to 89%), synchronous- recti?er topology with the newest components and time-tested, fully automated, smt-on-pcb construction, these uep models are able to bring you 15-30w in the standard 2" x 1" package from which most competitors can only get 5-10w. all ueps deliver their full output power over ambient temperature ranges from C40 c to as high as +70 c (model and input voltage dependent) without heat sinks or supplemental forced-air cooling. devices derate to +100 c. output voltages are 3.3, 5, 12 or 15 volts. input voltage ranges are 10-18v ("d12" models), 18-36v ("d24" models) or 36-75v ("d48") models. all models fea - ture input pi ?lters, input undervoltage and overvoltage lockout, input reverse-polarity protection, output overvoltage protection, output current limiting, and continuous short-circuit protection. standard features also include on/off control and output-trim. all models are certi?ed to iec950, ul1950 and en60950 safety requirements for operational insulation. "d48" models (36-75v inputs) are ce marked. uep series dc/dcs are packaged in low-cost, light-weight, diallyl phthalate (ul94v-0 rated) plastic packages with standoffs. emc compliance is achieved via a low-noise design rather than through expensive metal shielding. inno va ti on and ex c el l e n c e ? ? + i n p u t ( 1 ) + o u t p u t ( 4 ) p w m c o n t r o l l e r o p t o i s o l a t i o n u v l o & o v l o c o m p a r a t o r s s w i t c h c o n t r o l r e f e r e n c e & e r r o r a m p C o u t p u t ( 5 ) t r i m ( 6 ) C i n p u t ( 2 ) o n / o f f c o n t r o l ( 3 ) 3.3v and 5v-output models use the synchronous-recti?er con?guration shown above. 12v and 15v-output models employ a standard, diode-recti?cation architecture. datel, inc., mans?eld, ma 02048 (usa) tel: (508)339-3000, (800)233-2765 fax: (508)339-6356 email: sales@datel.com internet: www.datel.com ? ? ? ? ? ? ? ? ? ? ? ? ? models include 3.3v @ 4.5a or 6a 5v @ 3.5a or 6a 12v @ 1.4a 15v @ 1.2a choice of 3 input ranges: 10-18v, 18-36v, 36-75v guaranteed ef?ciencies to 89% 15-30 watts in 1" x 2" package 340khz synchronous-recti?er topologies C40 to +60/70 c ambient w/o derating fully isolated (1500vdc); i/o protected trim and on/off control ul1950/en60950 certi?ed ce mark (75v in models)

uep models 1 5 - 3 0 w , s i n g l e o u t p u t d c / d c c o n v e r t e r s input overvoltage/undervoltage shutdown and start-up threshold under normal start-up conditions, devices will not begin to regulate until the ramping-up input voltage exceeds the start-up threshold voltage (35v for "d48" models). once operating, devices will not turn off until the input voltage drops below the undervoltage shutdown limit (34v for "d48" models). subsequent re-start will not occur until the input is brought back up to the start-up threshold. this built in hysteresis prevents any unstable on/off situations from occurring at a single input voltage. input voltages exceeding the input overvoltage shutdown speci?cation listed in the performance/functional speci?cations will cause the device to shut - down. a built-in hysteresis of 0.6 to 1.6 volts for all models will not allow the converter to restart until the input voltage is suf?ciently reduced. the two 6 amp models do not feature overvoltage shutdown and withstand surges to 100v without shutting down. for custom overvoltage protection, contact datel. input reverse-polarity protection if the input-voltage polarity is accidentally reversed, an internal diode will become forward biased and likely draw excessive current from the power source. if the source is not current limited (<10a) nor the circuit appropriately fused, it could cause permanent damage to the converter. on/off control the input-side, remote on/off control function (pin 3) can be ordered to operate with either polarity (negative polarity available for 12 and 15 volt models only). positive-polarity devices (standard, no part-number suf?x) are enabled when pin 3 is left open or is pulled high (+13v to v in applied with respect to Cinput, pin 2, (see figure 2). positive-polarity devices are disabled when pin 3 is pulled low (0-0.8v with respect to Cinput). negative-polarity devices are off when pin 3 is open or pulled high (+2.4v to +10v), and on when pin 3 is pulled low (0-0.5v). see figure 3. dynamic control of the remote on/off function is best accomplished with a mechanical relay or an open-collector/open-drain drive circuit (optically isolated if appropriate). the drive circuit should be able to sink appropriate current (see performance specs) when activated and withstand appropriate voltage when deactivated. applying an external voltage to pin 3 when no input power is applied to the converter can cause permanent damage to the converter. start-up time the v in to v out start-up time is the interval of time where the input voltage crosses the turn-on threshold point, and the fully loaded output voltage enters and remains within its speci?ed accuracy band. actual measured times will vary with input source impedance, external input/output capaci - tance, and load. the uep series implements a soft start circuit that limits the duty cycle of the pwm controller at power up, thereby limiting the input inrush current. the on/off control to v out start-up time assumes the converter has its nominal input voltage applied but is turned off via the on/off control pin. the speci?cation de?nes the interval between the time at which the converter is turned on and the fully loaded output voltage enters and remains within its speci?ed accuracy band. similar to the v in to v out start-up, the on/off control to v out start-up time is also governed by the internal soft start circuitry and external load capacitance. current limiting when output increases to 120% to 190% of the rated output current, the dc/dc converter will go into a current limiting mode. in this condition the output voltage will decrease proportionately with increases in output cur - rent, thereby maintaining a somewhat constant power dissipation. this is commonly referred to as power limiting. current limit inception is de?ned as the point where the full-power output voltage falls below the speci?ed tolerance. see performance/functional speci?cations. if the load current being drawn from the converter is signi?cant enough, the unit will go into a short circuit condition. see "short circuit condition." 3 2 1 200k +i np ut 13v circuit 5v circuit Ci nput on /o ff cont ro l 3 2 1 +i np ut Ci nput on /o ff cont ro l figure 2. driving the positive polarity on/off control pin figure 3. driving the negative polarity on/off control pin 5
uep series 1 5 - 3 0 w , s i n g l e o u t p u t d c / d c c o n v e r t e r s short circuit condition when a converter is in current limit mode the output voltages will drop as the output current demand increases. if the output voltage drops too low, the magnetically coupled primary side voltages will also drop, thereby shutting down the pwm controller. following a time-out period, the pwm will restart, causing the output voltage to begin ramping to its appropriate value. if the short-circuit condition per - sists, another shutdown cycle will be initiated. this on/off cycling is referred to as "hiccup" mode. the hiccup cycling reduces the average output current, thereby preventing internal temperatures from rising to excessive levels. the uep is capable of enduring an inde?nite short circuit output condition. thermal shutdown these uep converters are equipped with thermal shutdown circuitry. if environmental conditions cause the internal temperature of the dc/dc converter rises above the designed operating temperature (typically 118c case), a precision temperature sensor will power down the unit. when the internal temperature decreases below the threshold of the temperature sensor the unit will self start. . output overvoltage protection output voltages are monitored for an overvoltage condition via magnetic coupling to the primary side. if the output voltage should rise to a level which could be damaging to the load circuitry, the sensing circuitry will power down the pwm controller causing the output voltages to decrease. following a time-out period the pwm will restart, causing the output voltages to ramp to their appropriate values. if the fault condition persists, and the output voltage again climbs to excessive levels, the overvoltage circuitry will initiate another shutdown cycle. this on/off cycling is referred to as "hiccup" mode. 6
