Flyback & Forward PWM Controllers with Integrated MOSFET
Features Precision Fixed Operating Frequency (50kHz) Low Start-up Current(Typ. 100uA) Pulse by Pulse Current Limiting Over Current Protection Over Voltage Protection (Min. 25V) Internal Thermal Shutdown Function Under Voltage Lockout Internal High Voltage Sense FET Auto-Restart Mode
DescriptionThe Fairchild Power Switch(FPS) product family is specially
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 integrates the fixed frequency
oscillator, the under voltage lock-out, the leading edge
blanking, the optimized gate turn-on/turn-off driver, the
thermal shutdown protection, the over voltage protection,
and the temperature compensated precision current sources
for the loop compensation and the fault protection circuitry.
Compared to a discrete MOSFET and a PWM controller or
an RCCsolution, a 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 design in a flyback converter.
