100 Watt
Single Output Regulated, 2:1 Input Range
Under-voltage lockout with a soft start
With a soft start and adjustable output voltage, our 100 watt single output DC-DC converter features under-voltage lockout, input reverse protection and an industry standard half-brick footprint. This design also has a six-sided continuous shield, an input to output basic insulation of 2250 Vdc and a bus terminal block option.
