STEVAL-VP12201B 15 V/200 mA buck converter based on VIPER122 Data brief
●Description
■The STEVAL-VP12201B evaluation board implements a 15 V-3 W buck converter mains designed for general purpose applications, operating from 85 to 265 V-AC.
■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 he 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.
●Features
■Universal input mains range: 85–265 V-AC
■Frequency: 50-60 Hz
■Output voltage: 15 V
■Output current: 200 mA
■Very compact size
■Stand-by mains consumption: < 30mW at 230 V-AC
■Average efficiency: > 77%
■Tight line and load regulation over the entire input and output range
■Meets IEC55022 Class B conducted EMI even with reduced EMI filter, thanks to the frequency jittering feature
■WEEE compliant
■RoHS compliant
