Part Number: 5L0380R, KA5L0380R
Functions: Power Management IC
Package: SIP 4 Pin Type
Manufacturer: Fairchild Semiconductor
The 5L0380R is Power Switch(FPS).
The 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.
• Precision Fixed Operating Frequency (100/67/50kHz)
• 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
1. Power MOSFET: The integrated power MOSFET allows for efficient switching and control of power in the application.
