DESCRIPTION

VIPer20/20A, 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 / 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 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.
