SMT40C Series 12 Vin single output DC-DC CONVERTERS • • • • • • • • • C Class Non-isolated 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. 2 YEAR WARRANTY SPECIFICATIONS All specifications are typical at nominal input Vin = 12 V, full load at 25 °C unless otherwise stated OUTPUT SPECIFICATIONS Voltage adjustability GENERAL SPECIFICATIONS (See Note 5) 0.9-5.0 Vdc Output setpoint accuracy 1.0% trim resistors ±3.0% Line regulation Low line to high line ±0.2% max.

It is no longer necessary to purchase a variety of modules in order to cover different output voltages. The output voltage can be trimmed in a range of 0.9 Vdc to 5.0 Vdc. When the SMT40C series converter leaves the factory the output has been adjusted to the default voltage of 0.9 V. Notes 1 2 3 4 5 6 7 8 9 10 11 12 13 14 Measured as per recommended set-up. 2 x Cin = 270 µF (20 mΩ ESR max, 3 x Cout = 680 µF (10 mΩ ESR max). di/dt = 10 A/µs, Vin = Nom, Tc = 25 °C, load change = 0.50 lo max. to 0.75 lo max. and 0.75 lo max. to 0.50 lo max. External input fusing is recommended. Measured with external filter. See Application Note 170 for details. Uses external resistor from trim pin to output ground. See Application Note 170 for details. Signal line assumed <3 m in length. This product is only for inclusion by professional installers within other equipment and must not be operated as a stand alone product. Power-up is the time from application of dc input to Power Good enabled. Remote ON/OFF is from ON/OFF asserted high to power good enabled. See Application Note 170 for operation above 50 ºC. See Application Note 170 for ripple current requirements. These models have a wide trim output. The unit has an output of 0.9 Vdc to 5 Vdc. An external resistor adjusts the output voltage. For redundant current sharing applications that use ORing diodes to separate the outputs, please add the suffix ‘-S’ to the part number, e.g. SMT40C-12SADJ-SJ. Please refer to Application Note 170 for further details. TSE RoHS 5/6 (non Pb-free) compliant versions may be available on special request, please contact your local sales representative for details. NOTICE: Some models do not support all options.
