Green Mode Fairchild Power Switch is a type of power switch that is designed for use in power supplies and other applications that require high efficiency and low power consumption. It is a type of switching regulator that uses a pulse width modulation (PWM) technique to regulate the output voltage.

The Green Mode Fairchild Power Switch is named after its environmentally friendly design, which minimizes power loss and reduces energy consumption. It is designed to operate in a low-power standby mode when there is no load demand, which helps to conserve energy and reduce standby power consumption.

5H0165R is Fairchild Power Switch. The Fairchild Power Switch(FPS) product family is specially designed for an off-line SMPS with minimal external components. The Fairchild Power Switch(FPS) consist of high voltage power SenseFET and current mode PWM IC.

The Fairchild Power Switch(FPS) consist of high voltage power SenseFET and current mode PWM IC. Included PWM controller features integrated fixed oscillator, under voltage lock out, leading edge blanking, optimized gate turn-on/turn-off driver, thermal shut down protection, over voltage protection, and temperature compensated precision current sources for loop compensation and fault protection circuitry compared to discrete MOSFET and controller or RCC switching converter solution, The Fairchild Power Switch(FPS) can reduce total component count, design size, weight and at the same time increase efficiency, productivity, and system reliability. It is well suited for cost effective design of flyback converters.
