VIPER12A DIP-8 Power Distribution Switch

VIPer12A Low Power Offline Switched-Mode Power Supply Primary Switcher IC – DIP-8 Package

VIPer12A – Low Power SMPS Primary Switcher IC, The VIPER12A is a Low power offline switched-mode power supply primary switcher that combines a dedicated current mode PWM controller with a high voltage power MOSFET on the same silicon chip. The VIPER12A combines a dedicated current mode PWM controller with a high voltage power MOSFET on the same silicon chip.  Typical applications cover offline 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 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 and overvoltage protection in HICCUP mode. This product is known as VIPER12AS-E, VIPER12ASTR-E, VIPER12ADIP-E, VIPer12A.
