DESCRIPTION
VIPer50?/50A make 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 / 1.5A).
Typical applications cover off line power supplies
with a secondary power capability of 25W in wide
range condition and 50W 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.
