VIPER20A,Off-Line Switch Mode Power Supply SMPS Controller with Integrated Power MOSFET, TO-220-5

The VIPER20A is a high-performance off-line switch mode power supply (SMPS) controller that combines a state-of-the-art PWM controller with a 700V avalanche-rugged MOSFET. Designed for flyback, forward, and buck-boost topologies, this device offers high efficiency, low standby power consumption, and robust protection features. Its burst mode operation enables compliance with stringent energy standards like the "Blue Angel."

The VIPER20A supports a wide range of AC input voltages and provides adjustable switching frequency up to 200 kHz. Housed in a TO-220-5 package, it is ideal for applications requiring high reliability, such as industrial power supplies, battery chargers, and consumer electronics.
