TEA1654 is a high performance green power control chip launched by Philips company, which supports 70-276V AC power supply and has a very low number of external components.
The Philips TEA1654 is an integrated controller for compact flyback converters operating directly from rectified universal mains. It features high integration with a low external component count and utilizes proprietary BCD800 technology for direct start-up.
The device supports multi-mode operation including quasi-resonant, fixed frequency PWM, and cycle skipping to optimize efficiency across all power levels. Key protection features include overvoltage, short winding, undervoltage, and overtemperature protection.
