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.

The ultra wide output voltage trim range offers major advantages to users who

select the SMT20C series. 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.
