Description

Description
The FSQ0170RNA, FSQ0270RNA, FSQ0370RNA 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.
Features
Internal Avalanche Rugged 700V SenseFET
Consumes only 0.8W at 230 VAC& 0.5W Load with Burst-Mode Operation
Precision Fixed Operating Frequency, 100kHz
Internal Start-up Circuit and Built-in Soft-Start
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
Applications
Auxiliary Power Supply for PC and Server
SMPS for VCR, SVR, STB, DVD & DVCD Player, Printer, Facsimile & Scanner
Adapter for Camcorder
