Wurth Elektronik MagI³C Power Module Step-Down Regulator for WPMDB

The VDRM series of the MagI³C Power Module family provide a fully integrated DC-DC power supply including the buck switching regulator and inductor in a package. The WPMDU1251501 offers high efficiency and delivers up to 2.5A of output current. It operates from 7V input voltage up to 50V. It is designed for fast transient response. It is available in a standard industrial high power density BQFN-41 (9 x 11 x 2.8mm) package with good thermal performance. The VDRM regulators have an on-board protection circuitry to guard against thermal overstress and electrical damage featuring thermal shutdown, over-current, short-circuit, overvoltage and undervoltage protections.
