Description
The Fairchild Power Switch(FPS) product family are spe-
cially designed for an off-line SMPS with minimal external
components. The Fairchild Power Switch(FPS) consists of a
high voltage power SenseFET and a current mode PWM IC.
Included PWM controller features the integrated oscillator to
be synchronized with the external sync, the under voltage
lockout, the optimized gate turn on/turn off driver, the ther-
mal shutdown protection, the over voltage protection, and
the temperature compensated precision current sources for
the loop compensation and the fault protection circuitry.
Compared with a discrete MOSFET and a controller or a
RCC switching converter solution, the Fairchild Power
Switch(FPS) can reduce the total component count, design
size, and weight and at the same time increase efficiency,
productivity, and system reliability. It has a basic platform
well suited for the cost effective monitor power supply.
