exb250 series single output ?high efficiency topology, 90% typical at 3.3v ?industry standard footprint ?wide baseplate temperature, -40?c to +100?c (natural convection) ?90% to 110% output trim ?no minimum load ?overvoltage protection ?remote on/off the exb250 is a new high efficiency, open frame, isolated 165 watt converter series in an industry standard half-brick footprint. the exb250 delivers very high output current at low voltages, and excellent useable power density for today's high end applications. the design takes advantage of open frame construction to provide a low weight, low thermal impedance baseplate design. the seven models in the series feature an input voltage range of 33 to 75vdc and are available in output voltages of 12v, 5v, 3.3v, 2.5v, 1.8v, 1.5v and 1.2v. the output voltage on each model is adjustable from 90% to 110% of the nominal value. typical efficiencies for the models are 90% for the 3.3v, 88% for the 2.5v and 87% for the 1.8v version. the exb250 series also has a remote on/off capability. overcurrent and overvoltage protection features are included as standard. with full international safety approval including en60950 (t?v rheinland) and ul/cul1950, the exb250 reduces compliance costs and time to market. specification all specifications are typical at nominal input, full load at 25 c unless otherwise stated page 1 [ 2 year warranty ] new product t?v international safety standard approvals ul/cul : ul1950 file no. e135734 t?v t?v rheinland certificate no. r2174184 cb scheme no. us-tuvr-1085 emc characteristics conducted emissions en55022 (see note 2) level a en55022 (see note 2) level b immunity: esd air en61000-4-2 8kv (np), 15kv (np) esd contact en61000-4-2 6kv ((np), 8kv (np) radiated field enclosure en61000-4-3 10v/m (np) conducted (dc power) en61000-4-6 10v (np) conducted (signal) en61000-4-6 10v (np) input transients ets 300 132-2, etr 283 general specifications efficiency see table operational input/output 1500vdc input/baseplate 1500vdc switching frequency fixed 400khz typ. approvals and en60950 (t?v rheinland) standards (see note 4) ul/cul1950 material flammability ul94v-0 weight 73g (2.6oz) mtbf mil-hdbk-217f >224,000 hours @ 40?, 100% load ground benign environmental specifications thermal performance operating baseplate -40? to +100? temperature non-operating -40? to +125? output specifications voltage adjustability 90% to 110% set point accuracy ?.6% max. line regulation 1v2 model ?.2% max. low line to high line all other models ?.1% max. load regulation full load to min. load ?.2% max. minimum load 0% overshoot at turn-on and turn-off none undershoot 1.2v, 1.5v, 1.8v. 2.5v none and 3.3v models ripple and noise 5hz to 20mhz 60mv pk-pk 20mv rms transient response 6% max. deviation (see note 1) 150? recovery to within total error band input specifications input voltage range 48vin nominal 33 to 75vdc input current no load 145ma max. remote off 35ma max. input current (max.) 5.7a max. @ io max.
