1. Introduction
This document is an engineering report describing measured performance of the
FSL206MR.
1.1. General Description
The FSL206MR integrated Pulse Width Modulator (PWM) and SenseFET is specifically
designed for high-performance offline Switched-Mode Power Supplies (SMPS) with
minimal external components. This device is an integrated high-voltage power regulator
that combines an avalanche-rugged SenseFET with a current mode PWM control block.
The integrated PWM controller includes: 7.8V regulator for no bias winding, UnderVoltage Lockout (UVLO) protection, Leading-Edge Blanking (LEB), an optimized gate
turn-on/turn-off driver, EMI attenuator, Thermal Shutdown (TSD) protection,
temperature-compensated precision current sources for loop compensation, and faultprotection circuitry. Protections include Overload Protection (OLP), Over-Voltage
Protection (OVP), Abnormal Over-Current Protection (AOCP), and Line Under-Voltage
Protection (LUVP). During startup, the FSL206MR offers good soft-start performance.
.
The internal high-voltage startup switch and the Burst-Mode operation with very low
operating current reduce the power loss in Standby Mode. As a result, it is possible to
reach power loss of 150mW with no-bias winding and 25mW with bias winding at noload condition when the input voltage is 265V

LIFE SUPPORT POLICY
FAIRCHILD’S PRODUCTS ARE NOT AUTHORIZED FOR USE AS CRITICAL COMPONENTS IN LIFE SUPPORT DEVICES OR SYSTEMS
WITHOUT THE EXPRESS WRITTEN APPROVAL OF THE PRESIDENT OF FAIRCHILD SEMICONDUCTOR CORPORATION.
As used herein:1.
Life support devices or systems are devices or systems which, (a)
are intended for surgical implant into the body, or (b) support or
sustain life, or (c) whose failure to perform when properly used in
accordance with instructions for use provided in the labeling, can be
reasonably expected to result in significant injury to the user.
2. A critical component is any component of a life support device or
system whose failure to perform can be reasonably expected to
cause the failure of the life support device or system, or to affect its
safety or effectiveness.
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.
