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.
