STMicroelectronics STEVAL-VP12201B Evaluation Board
STMicroelectronics STEVAL-VP12201B Evaluation Board implements a 15V/220mA buck converter based on the VIPER122 high-voltage converter. The VIPER122 converter operates at a fixed frequency of 60kHz with frequency jittering and meets electromagnetic disturbance standards. This evaluation board features small size, minimal BOM, high efficiency, low standby consumption, tight line, and load regulation. The STEVAL-VP12201B evaluation board offers Burst mode operation that allows low consumption under no load and reduces the average switching frequency to minimize all frequency-related losses.
