1. General Introduction
This document describes a 65W power supply using FAN6754AMR and FAN6204MY
synchronous rectification IC. This power supply is targeted towards power adapters and
open-frame consumer products.
With the internal high-voltage startup circuitry, the power loss due to bleeding resistors is
eliminated. To further reduce power consumption, FAN6754AMR is manufactured using
the BiCMOS process. This allows an operating current of only 1.5mA and low startup
current of 30μA. Built-in synchronized slope compensation ensures the stability of peak-
current-mode control. In addition, FAN6204MY improves conduction losses in heavy
load, and the SR controller stops all SR switching operation to reduce the operating
current in light load.

ANTI-COUNTERFEITING POLICY
Fairchild Semiconductor Corporation's Anti-Counterfeiting Policy. Fairchild's Anti-Counterfeiting Policy is also stated on our external website,
www.fairchildsemi.com, under Sales Support.
Counterfeiting of semiconductor parts is a growing problem in the industry. All manufacturers of semiconductor products are experiencing
counterfeiting of their parts. Customers who inadvertently purchase counterfeit parts experience many problems such as loss of brand reputation,
substandard performance, failed applications, and increased cost of production and manufacturing delays. Fairchild is taking strong measures to
protect ourselves and our customers from the proliferation of counterfeit parts. Fairchild strongly encourages customers to purchase Fairchild parts
either directly from Fairchild or from Authorized Fairchild Distributors who are listed by country on our web page cited above. Products customers buy
either from Fairchild directly or from Authorized Fairchild Distributors are genuine parts, have full traceability, meet Fairchild's quality standards for
handling and storage and provide access to Fairchild's full range of up-to-date technical and product information. Fairchild and our Authorized
Distributors will stand behind all warranties and will appropriately address any warranty issues that may arise. Fairchild will not provide any warranty
coverage or other assistance for parts bought from Unauthorized Sources. Fairchild is committed to combat this global problem and encourage our
customers to do their part in stopping this practice by buying direct or from authorized distributors.
