These modules provide a precisely regulated output voltage from 0.8Vdc to 5.5Vdc, programmable via an external resistor. Their openframe construction and small footprint enable designers to develop cost- and space-efficient solutions. Standard features include remote On/Off, adjustable output voltage, remote sense, active current sharing between parallel modules, output voltage sequencing of multiple modules, overcurrent, overvoltage, and overtemperature protection. - UL...
