VIPER12A Description

Short technical summary and product information.

The VIPER12A from STMicroelectronics is a highly integrated primary switcher for off-line Switched-Mode Power Supplies (SMPS). It combines a current mode PWM controller with a high-voltage Power MOSFET on a single chip, simplifying design and reducing component count.

Key electrical specifications include a fixed switching frequency of 60kHz and a wide VDD operating voltage range from 9V to 38V. The device offers typical power capabilities of 8W for SO-8 and 13W for DIP-8 packages at European mains voltage (195-265 Vac), and 5W for SO-8 and 8W for DIP-8 at universal mains voltage (85-265 Vac).

This component is designed for applications such as battery charger adapters, standby power supplies for TVs and monitors, and auxiliary supplies for motor control. It features built-in protection mechanisms including overtemperature, overcurrent, and overvoltage protection with auto-restart, as well as auxiliary undervoltage lockout with hysteresis.

The VIPER12A is available in DIP-8 and SO-8 package types, suitable for various mounting requirements.
