5V/100mA high voltage optimized buck converter based on VIPer013BLS

STEVAL-VP013B1B

Overview

The STEVAL-VP013B1B is a compact and efficient solution for AC-DC power supplies, which can convert voltages from the main line down to 5 V output.

The board is highly efficient and features extremely low input power consumption under no load and light load conditions due to the low current consumption and low V_CC voltage of the VIPer013B. Also, the pulse skip feature embedded in the IC eliminates inductor flux-runaway that is typically present during the startup phase of a buck converter.
