Technology, bines 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 / 0.5A). Typical applications cover off line power supplies with a secondary power capability of 10W in wide range condition and 20W in single range or with doubler configuration. It is patible from both primary or secondary regulation loop despite using around 50% less ponents...
