The device 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.主要特性
- 1050 V avalanche-rugged power MOSFET
- allowing ultra-wide VAC input range to be covered
