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 VCC 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.
