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 V
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.
