FSQ100

FSQ100 系列 20 V 73 KHz 通孔 绿色模式 Fairchild 功率 开关 - DIP-8

Description

The consists of an integrated Pulse Width Modulator PWM and SenseFET, specifically designed for high-performance, off-line, Switch-Mode Power Supplies SMPS with minimal external components. This device is an integrated high-voltage power switching regulator that combines a VDMOS SenseFET with a voltage mode PWM control block. The integrated PWM controller features include a fixed 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.
