SMT30C Series 12 Vin single output DC-DC CONVERTERS C Class Non-isolated 1 NEW Product 30 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 Available RoHS compliant The SMT30C series is a new high density open-frame, non-isolated converter for space sensitive applications. SMT30C 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 30 A load. An external resistor adjusts the output voltage from its pre-set value of 0.9 V to any value up to the 5 V maximum. Typical efficiency is 91%. The series offers remote ON/OFF and over-current protection as standard. With full international safety approvals including EN60950 and Ul/cUL60950, the SMT30C 2 YEAR WARRANTY 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 SPECIFICATIONS OUTPUT SPECIFICATIONS INPUT SPECIFICATIONS (CONTD.)

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 SMT30C converter leaves the factory the output has been adjusted to the default voltage of 0.9 V. NNootteess 1 Uses external resistor from TRIM to ground. See Application Note 170 for details. 2 Measured with external filter. See Application Note 170 for details. 3 di/dt = 10 A/s, Vin = Nom, Tc = 25 C, load change = 0.50 lo max. to 0.75 lo max, and vice versa. 4 External input fusing recommended. 5 Power up is the time from application of dc input to POWER GOOD high. Remote ON/OFF asserted high to POWER GOOD high. 6 Signal line assumed <3 m in length. 7 This product is only for inclusion by professional installers within other equipment and must not be operated as a stand alone product. 8 See Application Note 170 for operation above 50 C. 9 See Application Note 170 for more details. 10 For redundant current sharing applications that use ORing diodes to separate the outputs, please add the suffix -S to the part number, e.g. SMT30C-12SADJ-SJ. Please refer to Application Note 170 for further details. 11 TSE RoHS 5/6 (non Pb-free) compliant versions may be available on special request, please contact your local sales representative for details. 12 NOTICE: Some models do not support all options.
