5L0380R IC in Pakistan

The 5L0380R is a Fairchild Power Switch (FPS) IC designed for switch-mode power supplies (SMPS). It integrates a high-voltage power MOSFET with a current-mode PWM controller, reducing external components. Key features include pulse-by-pulse current limiting, over-voltage protection, thermal shutdown, and an auto-restart mode for enhanced safety and reliability. It operates at a fixed frequency and is ideal for adapters, chargers, and power supplies.
