High-voltage converters cut PCB component cost

The VIPER31 series of devices are the latest additions to the VIPerPlus family from STMicroelectronics and have been optimised for the most popular PSU topologies, flyback, buck and buck boost in isolated and non-isolated forms.

They are available at distributor Anglia Components.

These high-voltage converters smartly integrate an 800 V avalanche rugged power MOSFET with PWM current-mode control helping designers to meet the latest energy saving standards whilst simplifying the design and reducing PCB component count.

The VIPER31 series meets the most stringent energy-saving standards with its very low power consumption and operates in pulse frequency modulation at light load. 

The devices feature high conversion efficiency performing low power consumption also under no-load condition, below 20mW with a 230V input, and over the wide supply voltage range.

Extremely rugged, the devices feature a range of integrated safety features including overvoltage, undervoltage, short-circuit, pulse-skipping and thermal shutdown protection.
