VIPER22A DIP-8 ,Low Power Off-Line SMPS Primary Switcher - 20W, 9V-38V

The VIPER22A DIP-8 is a highly efficient low power OFF-line SMPS primary switcher designed to integrate a PWM controller and a high voltage power MOSFET on a single silicon chip. With its fixed 60 kHz switching frequency and current mode control, this device delivers reliable performance in applications such as battery chargers, TV and monitor standby supplies, and motor controllers.

The integrated over-temperature, over-current, and over-voltage protection ensures robust operation in harsh environments. Offering automatic burst mode for low load conditions and high efficiency, the VIPER22A helps reduce power consumption, making it compliant with stringent global energy-saving requirements.

Key Features :
