STEVAL-VP22201B

STEVAL-VP22201B is an evaluation board implementing a 5V - 1.8W buck converter developed for general purpose applications operating from 85 to 265V AC. The reference design is built around the VIPer222XSTR offline high-voltage converter from the VIPerPlus family with 730V Power MOSFET and PWM current-mode control. The main characteristics of the evaluation board are its small size and minimal BOM, low stand-by consumption and tight line and load regulation over the entire input and output range. Extremely low consumption under no-load condition is ensured thanks to burst mode operation that reduces the average switching frequency and minimizes all frequency related losses.

• Universal input mains range from 85 to 265V AC
• 50 to 60Hz frequency
• 360mA output current
• Very compact size
• Stand-by mains consumption less than 18mW at 230V AC
• Tight line and load regulation over the entire input and output range
• Meets IEC55022 Class B conducted EMI even with reduced EMI filter
