Product Summary
VIPER50A-22-E, made using VIPower M0 echnology, combines on the same silicon chip a state-of-the-art PWM circuit together with an optimized, high voltage, Vertical Power MOSFET (700V/ 1.5A).
Typical applications of the VIPER50A-22-E cover offline power supplies with a secondary power capability of 25W in wide ange condition and 50W in single range or with doubler configuration. The VIPER50A-22-E is compatible from both primary or secondary regulation loop despite using around 50% less components when compared with a discrete solution.
