DESCRIPTION

The WPC10R is a family of high performance DC/DC

converters that offer regulated outputs over two input

voltage ranges of 18 - 36 and 28 - 75V and over a wide

operating temperature range of -40°C to +100°C without

derating.

The 350kHz switching frequency and forward con-

verter topology provide optimum performance in a space-

saving package. The design uses all surface mounted

components, including magnetics, to provide enhanced

reliability. All models will operate even under no-load

conditions, although a minimum load is specified for load

regulation measurement purposes. A metal package is

utilized for decreased radiated noise and an optional

remote enable feature allows low power standby opera-

tion.
