TEA1566 is an integrated circuit with features such as high integration and low power consumption, suitable for offline power supply applications.
The Philips TEA1566 GreenChip is a monolithic high-voltage integrated circuit designed for off-line switched-mode power supply (SMPS) applications ranging from 90 to 276 VAC. It combines analog and digital circuits to implement control functions, including an integrated 600 V MOSFET, a 5% accurate oscillator, and comprehensive fault protection features such as over-voltage, over-current, and over-temperature protection. The device supports both Buck and flyback topologies and interfaces with both primary and secondary side feedback.
