Overview
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 LimitApplications Auxiliary Power Supply for PC and Server SMPS for VCR, SVR, STB, DVD & DVCD Player, Printer, Facsimile & Scanner Adapter for Camcorder
