Fairchild Power Switches were commonly used in switch-mode power supplies (SMPS) to regulate and control the power flow efficiently. They integrated various features such as overvoltage protection, overcurrent protection, thermal shutdown, and other control mechanisms to ensure the safe and reliable operation of power supply systems.
7M0880 is Fairchild Power Switch. The Fairchild Power Switch FS7M-series is an integrated Pulse Width Modulator (PWM) and Sense FET specifically designed for high performance offline Switch Mode Power
Supplies (SMPS) with minimal external components. This device is an integrated high voltage power switching regulator which combine an avalanche rugged Sense FET with a current mode PWM control block. The PWM controller includes integrated fixed frequency oscillator, under voltage lockout, leading edge blanking (LEB), optimized gate driver, soft start, temperature compensated precise current sources
for a loop compensation and self protection circuitry.
