A Flyback PWM (Pulse Width Modulation) Controller is an essential component in a flyback converter, which is a type of switched-mode power supply (SMPS) topology commonly used for power conversion and voltage regulation. The flyback converter is known for its ability to provide galvanic isolation between the input and output, making it suitable for a wide range of applications, including power adapters, battery chargers, and LED drivers.
Applications:
1. Single Stage High PF Flyback AC/DC SMPS
2. LED Lighting Power
