SMT40C-12SADJ-SJ

SMT40C Series DC-DC CONVERTERS • • • • • • C Class Non-isolated 12 Vin single output 1 NEW Product • • • 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 spacesensitive applications. Each model has a wide input range of 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. All specifications are typical at nominal input Vin = 12 V, full load at 25 °C unless otherwise stated 2 YEAR WARRANTY SPECIFICATIONS OUTPUT SPECIFICATIONS Voltage adjustability (See Note 5) 0.9-5.0 Vdc ±3.0% ±0.2% max. ±1.5% max. 0 A/40 A At turn-on At turn-off (See Note 1) 1.0% max. 100 mV max. 50 mV pk-pk 15 mV rms 75 mV max. deviation 50 µs recovery to within regulation band Full load ±10% GENERAL SPECIFICATIONS Efficiency Switching frequency Approvals and standards Material flammability Weight Coplanarity MTBF Telcordia SR-332, method II @ 40 ºC Fixed (See Note 7) 92% typ. 300 kHz typ.
