Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers

will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor

product management systems do not have the ability to manage part nomenclature that utilizes an underscore

(_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain

device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated

device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please

email any questions regarding the system integration to Fairchild_questions@onsemi.com.

Description

The Fairchild Power Switch(FPS) product family is specially

designed for an off-line SMPS with minimal external

components. The Fairchild Power Switch(FPS) consists of a

high voltage power SenseFET and a current mode PWM IC.

Included PWM controller integrates the fixed frequency

oscillator, the under voltage lock-out, the leading edge

blanking, the optimized gate turn-on/turn-off driver, the

thermal shutdown protection, the over voltage protection,

and the temperature compensated precision current sources

for the loop compensation and the fault protection circuitry.

Compared to a discrete MOSFET and a PWM controller or

an RCCsolution, a Fairchild Power Switch(FPS) c an reduce

the total component count, design size and weight and at the

same time increase efficiency, productivity, and system

reliability. It has a basic platform well suited for the cost

effective design in either a flyback converter or a forward

converter

DISCLAIMER

FAIRCHILD SEMICONDUCTOR RESERVES THE RIGHT TO MAKE CHANGES WITHOUT FURTHER NOTICE TO ANY PRODUCTS HEREIN TO IMPROVE

RELIABILITY, FUNCTION, OR DESIGN. FAIRCHILD DOES NOT ASSUME ANY LIABILITY ARISING OUT OF THE APPLICATION OR USE OF ANY PRODUCT

OR CIRCUIT DESCRIBED HEREIN; NEITHER DOES IT CONVEY ANY LICENSE UNDER ITS PATENT RIGHTS, NOR THE RIGHTS OF OTHERS. THESE

SPECIFICATIONS DO NOT EXPAND THE TERMS OF FAIRCHILD’S WORLDWIDE TERMS AND CONDITIONS, SPECIFICALLY THE WARRANTY THEREIN,

WHICH COVERS THESE PRODUCTS.

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 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, and (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 a significant injury of the user.

2. A critical component in 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 w ebsite,

www .fairchildsemi.com, under Sales Support.

Counterfeiting of semiconductor parts is a growing problem in the industry. All manufacturers of semic onductor 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 abov e. 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 w ill appropriately address any warranty issues that

may arise. Fairchild will not prov ide any w arranty coverage or other assistance for parts bought from Unauthorized Sources. Fairchild is comm itted to combat this

global problem and encourage our customers to do their part in stopping this practice by buy ing direct or from authorized distributors.
