The LinkSwitch™-HP family of flyback power supply ICs incorporate a primary side regulated (PSR) controller and high-voltage power MOSFET in a single package. The IC family includes devices optimized for constant voltage (CV) operation at power ranges from 9W to 90 W. LinkSwitch-HP IC controller features +/-5% CV accuracy, selectable current limit, programmable latching or hysteretic OVP, UVP and OTP, improved overload power compensation over line, fast AC reset, and programmable shutdown delay time.
