VIPER12A DIP-8 Power Distribution Switch

Description

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. Features: Fixed 60 kHz switching frequency 9 V to 38 V wide range VDD voltage Current mode control Auxiliary Undervoltage lockout with hysteresis High voltage start-up current source Overtemperature, overcurrent, and overvoltage protection with auto-restart Specifications: Manufacturer Part No: VIPER12A Product Type: AC/DC Converters Output Voltage: 730 V Output Power: 8 W Input / Supply Voltage – Min: 9 V Input / Supply Voltage – Max: 38 V Switching Frequency: 60 kHz Number of Outputs: 1 Output Duty Cycle – Max: 16 % Operating Supply Current: 4.5 mA Minimum Operating Temperature: -40°C Maximum Operating Temperature: +150°C Mounting Style: Through Hole Package/Case: DIP-8 Pin Configuration Pin Number Pin Name Description 1,2 Source Source pin of the switching MOSFET 3 Feedback Feedback for the SMPS circuit 4 VDD Vdd voltage 9V to 38V 5,6,7,8 Drain Drain pin of the switching MOSET Application: Offline power supplies for battery charger adapters Standby power supplies for TV or monitors Auxiliary supplies for motor control Datasheet: VIPer12A
