Power Integrations LinkSwitch™-HP Off-Line Switchers
Power Integrations LinkSwitch™-HP Off-Line Switcher 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 90W. Power Integrations 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. These devices include a K package, an eSOP-12B low-profile surface-mount package for ultra-slim designs.
