Description

VIPer100-E, made using VIPower M0 Technology,

combines on the same silicon chip a state-of-the-

art PWM circuit together with an optimized, high

voltage, Vertical Power MOSFET (620V/ 3A).

Typical applications cover offline power supplies

with a secondary power capability of 50W in wide

range condition and 100W in single range or with

doubler configuration. 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 ability to operate in stand-by mode

without extra components.
