VIPER22ADIP-E

The VIPER22ADIP-E is a highly integrated off-line switcher with an 800V avalanche-rugged power section, a PWM control, and a protection circuitry. It is designed for low-power applications such as auxiliary power supplies, chargers, and adapters.

This device operates in a fixed-frequency PWM mode with a frequency of up to 60kHz. It features a current mode control that provides excellent line and load regulation, as well as a very low standby power consumption of less than 50mW at 265VAC.

The VIPER22ADIP-E includes a built-in high-voltage startup circuit that allows the device to be powered directly from the rectified mains, eliminating the need for an auxiliary winding or a separate bias voltage. This feature simplifies the design and reduces the overall cost of the application.

In terms of protection, the VIPER22ADIP-E includes features such as overload protection, short-circuit protection, and thermal shutdown. These protections ensure the safety and reliability of the application by preventing damage to the device and the connected components.

Overall, the VIPER22ADIP-E is a versatile and efficient off-line switcher that is suitable for a wide range of low-power applications. Its integrated features, high voltage capability, and protection circuitry make it an ideal choice for designers looking for a compact and reliable solution for their power supply designs.
