Fairchild Power Switch(FPS)
Features
• Precision Fixed Operating Frequency (100/67/50kHz)
• Low Start-up Current (Typ. 100uA)
• Pulse by Pulse Current Limiting
• Over Load Protection
• Over Voltage Protection (Min. 25V)
• Internal Thermal Shutdown Function
• Under Voltage Lockout
• Internal High Voltage Sense FET
• Auto-Restart Mode
Description
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. 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 has a basic platform well suited for cost-effective
design in either a flyback converter or a forward converter.
