AN-58 - LinkSwitch-HP Design Guide

The LinkSwitch-HP family is a highly integrated monolithic switcher IC designed for off-line power supplies. Output regulation is achieved using primary-side sense regulation (PSR) that gives accurate output regulation for designs up to 90 W / 117 W.

This application note is intended for engineers designing an isolated AC-DC flyback power supply using LinkSwitch-HP devices. It provides guidelines to enable an engineer to quickly select key components and also complete a suitable transformer design.
