1. Introduction

This engineering report describes a 2.04W power supply using a FSQ500L. This power supply is targeted for a flyback converter replaces linear power supplies with low cost and small size.

1.1. General Description

This device combines a current-mode Pulse Width Modulator (PWM) with a SenseFET and high-voltage regulator connected from the DRAIN pin to supply the V does not need to use bias winding and associated external components.

Using a SOT-223 package, FSQ500L reduces total size and weight while increasing efficiency, productivity, and system reliability. Using FSQ500L, this design example for

2.04W can be implemented with few external components and minimized cost.

1.2. Features

 Single-Chip 700V SenseFET Power Switch  Precision Fixed Operating Frequency: 130kHz  No-load consumption 250mW at 265V

with External Bias

 Internal Startup Switch  Soft-Start Time Tuned by External Capacitor  Under-Voltage Lockout (UVLO) with Hysteresis  Pulse-by-Pulse Current Limit  Overload Protection (OLP) and Internal Thermal Shutdown Function (TSD) with

Hysteresis

 Auto-Restart Mode  No Need for Auxiliary Bias Winding

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.
