VIPer53EDIP - E
VIPer53ESP - E
OFF-line Primary Switch
Features
■ Switching frequency up to 300kHz
■ Current mode control with adjustable limitation
■ Soft start and shut-down control
■ Automatic burst mode in standby condition
(“Blue Angel“ compliant )
■ Undervoltage lockout with Hysteresis
■ Integrated start-up current source
■ Over-temperature protection
■ Overload and short-circuit control
■ Overvoltage protection
■ In compliance with the 2002/95/EC European
Directive
Description
The VIPer53E combines an enhanced current
mode PWM controller with a high voltage
MDMesh Power MOSFET in the same package.
Typical applications cover offline power supplies
with a secondary power capability ranging up to
30W in wide range input voltage, or 50W in single
European voltage range and DIP-8 package and
40W in wide range input voltage, or 65W in single
European voltage range and PowerSO-10
package, with the following benefits:
– Overload and short-circuit events
controlled by feedback monitoring and
delayed device reset;
– Efficient standby mode by enhanced pulse
skipping.
– Integrated start-up current source is
disabled during normal operation to reduce
the input power.

1.1 Maximum rating
Stressing the device above the rating listed in the “Absolute Maximum Ratings” table may
cause permanent damage to the device. These are stress ratings only and operation of the
device at these or any other conditions above those indicated in the Operating sections of
this specification is not implied. Exposure to Absolute Maximum Rating conditions for
extended periods may affect device reliability. Refer also to the STMicroelectronics SURE
Program and other relevant quality documents.
