OBS SERIES SINGLE 2 5 W AT T k e y * * * * f e a t u r e s industry standard 2" x 2" package 12, 24, and 48V input versions 25 Watts of output power 100C baseplate operation * * * * trim and enable pins fixed frequency 1500 VDC isolation 6 sided shielding The OBS series of single output DC/DC converters provide up to 25W of output power in the industry standard 2" x 2" package and footprint. These units feature excellent efficiency, six sided shielding, and fixed switching frequency. With 100C case operation possible, the OBS series are especially suited to Telecom, Networking, and Industrial applications. These units are 100% surface mount construction, are fully compatible with production board washing processes, and are manufactured in IPD's ISO9001 factory. t e c h n i c a l s p e c i f i c a t i o n s i n p u t voltage range 12 VDC nominal 24 VDC nominal 48 VDC nominal reflected ripple input reverse voltage protection e f f . v s l o a d (4 8 V I N ) 10 - 20 VDC 18 - 36 VDC 34 - 75 VDC 25 mA shunt diode o u t p u t setpoint accuracy line regulation VIN min. - VIN max., IOUT rated load regulation IOUT min. - IOUT max., VIN nom. minimum output current dynamic regulation, loadstep Pk deviation settling time voltage trim range short circuit / overcurrent protection current limit threshold range, %Io rated OVP trip range OVP 1% 0.2% Vo 0.5% Vo 10 % 25% Io 4% Vo 500 uS 10% hiccup 110 - 140% 115 - 140%VOUT nom. hiccup g e n e r a l turn-on time: 24 & 48VIN , 12VIN remote shutdown remote shutdown reference switching frequency isolation input - output input - case (24Vin units) output - case (48 Vin units) temperature coefficient case temperature operating range (12V input max temp +85C) storage range humidity max, non-condensing vibration, 3 axes, 5 min each MTBF (Bellcore TR-NWT-000332) safety weight (approx.) 38 8 8 8 - I P D 4 7 3 C O N V e r t e r 2 6 6 8 10 ms, 300 ms (respectively) positive Vin negative 400 KHz 1500 VDC 500 VDC 500 VDC 0.03%/C -40 to +100C -40 to +125C 95% 5 g, 10-55Hz 1.8 x 106 hrs UL 1950, CSA 22.2-950, EN60950 1.9 oz. n o t e s MTBF predictions may vary slightly from model to model.
