VIPER20B General Description

VIPer20B™combines on the same silicon chip a state-of-the-art PWM circuit together with an optimized high voltage avalanche rugged Vertical Power MOSFET (400V 1.3A).

Typical applications cover off line power supplies with a secondary max power capability of 30W. It is compatible from both primary or secondary regulation loop despite using around 50% less components when compared with a discrete solution. Burst mode operation is an additional feature of this device, offering the possibility to operate in stand-by mode without extra components.
