Description

VIPer20-E/DIP-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/ 0.5A).

Typical applications cover offline power supplies

with a secondary power capability of 10W in wide

range condition and 20W 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.
