Green Mode Fairchild Power Switch (FPS™)

Features

Description

The FSQ0370 consists of an integrated Current Mode

Pulse Width Modulator (PWM) and an avalanche rugged

700V SenseFET. It is specifically designed for high-

performance offline Switched 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

Internal Avalanche Rugged 700V SenseFET

Consumes Only 0.8W at 230V_AC& 0.5W Load with

Burst-Mode Operation

Precision Fixed Operating Frequency: 100kHz

Internal Startup Circuit and Built-in Soft-Start

Pulse-by-Pulse Current Limiting, Auto-Restart Mode

optimized gate turn-on

/ turn-off driver, Thermal

Over-Voltage Protection (OVP), Overload

Protection (OLP), Internal Thermal Shutdown

Function (TSD)

Shutdown (TSD) protection, and temperature-

compensated precision current sources for loop

compensation and fault protection circuitry.

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 FSQ0370 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,

such as in PC auxiliary power supplies.

Applications

Auxiliary Power Supply for PC and Server

SMPS for VCR, SVR, STB, DVD, and DVCD Player

Printer, Facsimile, and Scanner
