1. This parameter applies when the start-up current source is OFF. This is the case when the V_DD voltage has reached V_DDon and remains above V_DDoff.
2. This parameter applies when the start up current source is on. This is the case when the V_DD voltage has not yet reached V_DDon or has fallen below V_DDoff.


Description

The VIPer22A-E combines a dedicated current mode PWM controller with a high voltage Power MOSFET on the same silicon chip.

VIPer22A-E 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 VIPer22A-E 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.
