DESCRIPTION
The VIPer32 combines a dedicated current mode
PWM controller with a high voltage Power
MOSFET on the same silicon chip. Typical
applications cover off line power supplies for VCR
or DVD players, set top boxes, etc. The internal
control circuit offers the following benefits:
– Large input voltage range on the VDD pin
together with automatic burst mode provides a
good performance in low load condition.
– Delayed overload protection by feedback
monitoring.
