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.
