DESCRIPTION

VIPer31SP combines on the same silicon chip a

PWM

control

dedicated

to

output

current

regulation together with an optimised high voltage

avalanche

rugged

vertical

power

MOSFET

(600V/1A). Typical applications cover battery

chargers with constant current and constant

voltage

output

characteristics,

without

any

optocoupler between primary and secondary

sections. Typical output power capability is 15 W

in wide range condition and 30 W in single range

or

with

doubler

configuration.

Burst

mode

operation is an additional feature of this device,

offering the possibility to operate in no load

condition with an input power as low as 1W. This

feature insures the compliance towards ”Blue

Angel” norm and other similar ones.
