VIPER22-LED-EV

低功率离线式开关电源初级切换器 Low power OFF-line SMPS primary switcher

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:

Features

■ Fixed 60 kHz switching frequency

■ 9 V to 38 V wide range VDDvoltage

■ Current mode control

■ Auxiliary undervoltage lockout with hysteresis

■ High voltage start-up current source

■ Overtemperature, overcurrent and overvoltage protection with auto-restart
