... Approved for basic insulation (-B suffix) Description The JBW050F Power Module is a dc-dc converter that operates over an input voltage range of 36 Vdc to 75 Vdc and provides a precisely regulated 3.3 Vdc output. The output is fully isolated from the input, allowing a versatile polarity configuration and grounding connections. The module has a maximum power rating typical full-load efficiency of 81% ...
