FSQ0170RNA, FSQ0270RNA

Green Mode Fairchild Power Switch (FPS™)

Features

Description

 Internal Avalanche Rugged 700V SenseFET

 Consumes only 0.8W at 230 V_AC& 0.5W Load with

Burst-Mode Operation

 Precision Fixed Operating Frequency, 100kHz

 Internal Start-up Circuit and Built-in Soft-Start

The FSQ0170RNA, and FSQ0270RNA, consists of an

integrated current mode Pulse Width Modulator (PWM)

and an avalanche-rugged 700V Sense FET. It is

specifically designed for high-performance off-line

Switch Mode Power Supplies (SMPS) with minimal

external components. The integrated PWM controller

features include: a fixed-frequency generating oscillator,

Under-Voltage Lockout (UVLO) protection, Leading

Edge Blanking (LEB), an optimized gate turn-on/turn-off

driver, Thermal Shutdown (TSD) protection, and

temperature compensated precision current sources for

loop compensation and fault protection circuitry.

 Pulse-by-Pulse Current Limiting and Auto-Restart

Mode

 Over-Voltage Protection (OVP), Overload Protection

(OLP), Internal Thermal Shutdown Function (TSD)

 Under-Voltage Lockout (UVLO)

 Low Operating Current (3mA)

 Adjustable Peak Current Limit

Compared to a discrete MOSFET and controller or RCC

switching converter solution, the FSQ0170RNA, and

FSQ0270RNA reduces total component count, design

size, and weight while increasing efficiency, productivity,

and system reliability. These devices provide a basic

platform that is well suited for the design of cost-effective

flyback converters, as in PC auxiliary power supplies.

Applications

 Auxiliary Power Supply for PC and Server

 SMPS for VCR, SVR, STB, DVD & DVCD Player,

Printer, Facsimile & Scanner

 Adapter for Camcorder
