Add to Cart:

VIPer22 is a low power offline smps IC in DIP package. Viper22A combines a dedicated current mode PWM controller with a high voltage power MOSFET on the same chip. Typical applications cover off line power supplies for LED lamp, battery charger adapters, standby power supplies, auxiliary supplies for motor control, etc. The internal control circuit offers the following benefits: Large input voltage range on the VDDpin accommodates changes in auxiliary supply voltage. This feature is well adapted to battery charger adapter configurations. Automatic burst mode in low load condition. Overvoltage protection in HICCUP mode.

Key Features

    Fixed 60 kHz switching frequency
