1 / 3 page 2 YEAR WARRANTY SMT40C Series 12 Vin single output All specifications are typical at nominal input Vin = 12 V, full load at 25 °C unless otherwise stated SPECIFICATIONS File Name: smt40c.pdf Rev (04): 16 Dec 2005 DC-DC CONVERTERS C Class Non-isolated 1 • 40 A current rating • Input voltage range: 10.2 Vdc - 13.8 Vdc • Output voltage range: 0.9 Vdc - 5.0 Vdc • Industry leading value • Cost optimized design • Excellent transient response • Output voltage adjustability • Pathway for future upgrades • Supports silicon voltage migration • Resulting in reduced design-in and qualification time • Designed in reliability: MTBF of >4 million hours per Telcordia SR-332 • Current share • Available RoHS compliant The SMT40C Series is a new high density open frame non-isolated converter for space- sensitive applications. Each model has a wide input range o f 10.2 Vdc to 13.8 Vdc and offers a wide 0.9 Vdc to 5.0 Vdc output voltage range with a 40 A load. An external resistor adjusts the output voltage from its pre-set value of 0.9 V to any value up to 5 V. Typical efficiencies are 92% at full load conditions. The SMT40C series offers remote ON/OFF and overcurrent protection as standard. With full international safety approval including EN60950 and UL/cUL60950, the SMT40C reduces compliance costs and time to market.
