Product Summary
The VIPER100A is a smps primary IC, which is using VIPower M0 Technology, combines on the same silicon chip a state-of-the-art PWM circuit together with an optimized high voltage avalanche rugged Vertical Power MOSFET (620V or 700V / 3A). Typical applications of VIPER100A cover off line power supplies with a secondary power capability of 50 W in wide range condition and 100W in single range or with doubler configuration. The VIPER100A 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.
