产品概述
描述
The STEVAL-VP12201B evaluation board implements a 15 V-3 W buck converter mains designed for general purpose applications, operating from 85 to 265 VAC.
It is built around the VIPER122 offline high-voltage converter of the VIPerPlus family with a 730 V Power MOSFET and PWM current mode control.
The STEVAL-VP12201B features include its small size and minimal BOM, high efficiency, low standby consumption, and tight line and load regulation over the entire input and output range.
Burst mode operation allows extremely low consumption under no load and reduces the average switching frequency to minimize all frequency related losses.
VIPER122 operates at a fixed frequency of 60 kHz with frequency jittering to meet electromagnetic disturbance standards.
