Description
The VIPer22A-E 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 battery charger adapters, standby power
supplies for TV or monitors, auxiliary supplies for
motor control, etc. The internal control circuit
offers the following benefits:
Large input voltage range on the VDD pin
accommodates changes in auxiliary supply
voltage. This feature is well adapted to battery
charger adapter configurations.
Automatic burst mode in low load condition.
Overvoltage protection in HICCUP mode.

A complete regulation scheme can achieve combined and accurate output characteristics.
Figure 4. presents a secondary feedback through an optocoupler driven by a TSM101. This
device offers two operational amplifiers and a voltage reference, thus allowing the regulation
of both output voltage and current. An integrated OR function performs the combination of
the two resulting error signals, leading to a dual voltage and current limitation, known as a
rectangular output characteristic. This type of power supply is especially useful for battery
chargers where the output is mainly used in current mode, in order to deliver a defined
charging rate. The accurate voltage regulation is also convenient for Li-ion batteries which
require both modes of operation.
