SMT40C Series

1 2 V i n s i n g l e o u t p u t

DC-DC CONVERTERS C Class Non-isolated

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 space-

sensitive 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.

2 YEAR WARRANTY

All specifications are typical at nominal input Vin = 12 V, full load at 25 °C unless otherwise stated
