1 / 3 page DC-DC CONVERTERS C Class Non-isolated 1 SMT15C Series 5 Vin and 12 Vin single output NEW Product File Name: smt15c.pdf Rev Rev (03): 16 Dec 2005 2 YEAR WARRANTY • 15 A current rating • Input voltage range: 4.5 Vdc to 5.5 Vdc or 10.2 Vdc to 13.8 Vdc • Output voltage range: 0.9 Vdc - 3.3/5.0 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 >7 million hours per Telcordia SR-332 • Available RoHS compliant The SMT15C series is a new high density open-frame, non-isolated converter for space sensitive applications. Each model has a wide input range (4.5 Vdc to 5.5 Vdc or 10.2 Vdc to 13.8 Vdc) and offers a wide 0.9 Vdc to 5.0 Vdc output voltage range with a 15 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 efficiencies for the models are 89% for the 5 V input version and 91% for the 12 V input version. The series offers remote ON/OFF and overcurrent protection as standard. With full international safety approvals including EN60950 and UL/cUL60950, the SMT15C 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 Voltage adjustability 5 Vin 0.9-3.3 Vdc (See Note 7) 12 Vin 0.9-5.0 Vdc Output setpoint accuracy 1.0% trim resistors ±2.5% Line regulation Low line to high line ±0.2% Load regulation Full load to min. load ±0.5% Min/max load 0 A/15 A Overshoot 5 Vin 3.0% max.
