APPLICATIONS
This WRN series is a high performance
2.5V to 15V ,2Amp ,12-Pin SIP (single
in-line package).Integrated switching
regulator (ISR),Synchrotron-rectified
design yields excellent efficiencies up to
97%.Short circuit protection with crowbar
function to reduce the short circuit current
to under 50mA of input current.
