- Available RoHS compliant The SMT20C Series is a new high density open frame non-isolated converter for space-sensitive 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.

See Application Note 169 for details. 5 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. 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 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. 9 See Application Note 169 for operation above 50 ºC. 10 See Application Note 169 for ripple current requirements. 11 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.

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.
