STMicroelectronics AN2753 VIPer17 Application Note

The VIPer17 is an offline power converter that integrates an advanced PWM controller with built-in BCD6 technology and an 800V avalanche rugged vertical power MOSFET. The device is suitable for 6W output power with a wide range input voltage (85VAC-270VAC) or 10W output power with a single range input voltage (85VAC-132VAC or 175VAC-265VAC). It offers the advantages of using few external components, providing several switch mode power supply protections, and very low standby consumption in no-load condition.
