LNK6778E

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.

Power Integrations LNK6778E LinkSwitch™-HP AC/DC Converter

Power Integrations LNK6778E LinkSwitch™-HP AC/DC Converter is a highly efficient, high power off-line switcher with Accurate Primary-Side Regulation (PSR). LinkSwitch™ monolithically integrates a controller and high-voltage power MOSFET into one package. This device uses an enhanced peak current mode PWM control scheme with multimode operation. This switch has a fully integrated soft-start for minimum start-up stress. LinkSwitch™ also has features such as bus overvoltage sense (line OV) and over temperature protection (OTP).
