1. Introduction

This document is an engineering report describing a 65 W power supply using FAN6604MR PWM controller. This power supply is targeted towards power adapters and open-frame for consumer products.

With the internal high-voltage startup circuitry, the power loss due to bleeding resistors is also eliminated. To further reduce power consumption, FAN6604MR is manufactured by using the BiCMOS process. This allows an operating current of 1.7 mA and low startup current of 30 μA. Built-in synchronized slope compensation ensures the stability of Peak Current Mode control.
