VIPer26K Converter Features High MOSFET Breakdown Voltage 1050V

The STMicroelectronics launched VIPer26K high-voltage converter comprises a 1050V avalanche-rugged N-channel power MOSFET that allow offline power supplies to combine a wide input-voltage range with the advantages of a simplified design. The VIPer26K MOSFET comes with buit-in Drain current-limit protection and features a senseFET connection for over-temperature protection. The VIPer26K MOSFET offers high voltage rating which eliminates the need for conventional stacked FETs and also associated passive components to achieve similar voltage capability.

The VIPer26K MOSFET comes with a built-in error amplifier, high-voltage startup circuitry, and current-mode PWM controller all integrated on-chip which makes it support all common switched-mode power supply topologies, including isolated flyback with secondary-side or primary-side regulation, non-isolated flyback with resistive feedback, buck, and buck-boost converters. The VIPer26K offers highest MOSFET breakdown voltage along with a complete set of integrated features making it an ideal solution for applications such as power supplies for 1-phase and 3-phase smart energy meters, air-conditioners, 3-phase industrial systems and LED lighting.
