Note:
1. This parameter applies when the start up current source is off. This is the case when the VDD voltage has reached VDDon and remains above VDDoff.

2. This parameter applies when the start up current source is on. This is the case when the VDD voltage has not yet reached VDDon or has fallen below VDDoff.




Description

The VIPer12A combines a dedicated current mode PWM controller with a high voltage Power MOSFET on the same silicon chip. VIPer12A 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 of VIPer12A 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.
