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 -40C to +100C 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.
