STMicroelectronics’ VIPer26K is a high voltage converter smartly integrating a 1050 V avalanche-rugged power section with a PWM current-mode control. The 1050 V-_BV power MOSFET allows to extend input voltage range and reduce the size of the DRAIN snubber circuit. This IC meets the most stringent energy-saving standards as it has very low consumption and operates in burst mode under light load.

The integrated HV startup, sense-FET, error amplifier, and oscillator with jitter allow a complete application to be designed with the minimum number of components.

The VIPer26K supports the most common SMPS topologies such as isolated flyback with optocoupler, primary-side regulation, non-isolated flyback with resistive feedback, buck, and buck-boost.
