DESCRIPTION

VIPer100™/100A,

made

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 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. 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 possibility to operate in stand-by

mode without extra components.
