SMT20C Series 5 Vin and 12 Vin single output DC-DC CONVERTERS • • • • • • • • C Class Non-isolated 1 NEW Product 20 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 to 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 SMT20C 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 3.3/5 V output voltage range with a 20 A load. An external resistor adjusts the output voltage from its pre-set value of 0.9 V to any value up to the maximum allowed value for that model. Typical efficiencies are 87% for the 5 V input version and 91% for the 12 V input version at full load conditions. The SMT20C series offers remote ON/OFF and overcurrent protection as standard. With full international safety approval including EN60950 and UL/cUL60950, the SMT20C 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 (See Note 5) INPUT SPECIFICATIONS (CONTD.) 5 V input models 12 V input models 0.9-3.3 Vdc 0.9-5.0 Vdc Output setpoint accuracy With 1.0% trim resistors Line regulation Low line to high line Load regulation ±2.5% 0 A/20 A Overshoot (at turn on) 5 V input models 12 V input models Ripple and noise 5 Hz to 20 MHz (See Note 1) 5 Vin 12 Vin 4.5 Vdc typ. 9.3 Vdc typ.

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 SMT20C series converter leaves the factory the output has been adjusted to the default voltage of 0.9 V.

At 12 V, 0.9 Vout, the max voltage deviation is 200 mV. External input fusing is recommended. Measured with external filter. See Application Note 169 for details. Uses external resistor from trim pin to output ground. Min value = 485 Ω for 5 V model, 280 Ω for 12 V model. See Application Note 169 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 169 for operation above 50 ºC. See Application Note 169 for ripple current requirements. These models have a wide trim output. 5 Vin has an output of 0.9 Vdc to 3.3 Vdc and 12 Vin has an output of 0.9 Vdc to 5 Vdc. An external resistor adjusts the output voltage. TSE RoHS 5/6 (non Pb-free) compliant versions may be available on special request, please contact your local sales representative for details.
