The STEVAL-VP26K01B reference design implements a 15?V-1.5?W buck converter for ultra-wide input voltage range auxiliary power supplies from 60 to 870?VDC or 90 to 600?VAC. The highly compact design offers tight line and load regulation over the entire input and output range.
The board represents a very low cost buck solution based on the new VIPER265KDTR offline high-voltage converter from the VIPerPlus family with 1050?V Power MOSFET and PWM current-mode control. It allows direct connection to ultra-wide range mains without the need for input an voltage limiter and/or stacked MOSFETs, therefore ensuring a minimal BOM.
The VIPER265KDTR operates at 60?kHz fixed frequency with frequency jittering to meet the EMC standard requirements.
