MagI3C Power Module VDRM – Variable Step Down Regulator Module

Wurth Elektronik GmbH & Co. KG, Germany. 

WPMDM1500602 / 171050601

MagI3C Power Module

VDRM – Variable Step Down Regulator Module

6V – 36V / 5A / 0.8V – 6V Output

DESCRIPTION

The VDRM series of the MagI³C Power Module family

provides a fully integrated DC-DC power supply including

the buck switching regulator and inductor in a package.

The 171050601 offers high efficiency and delivers up to

5A of output current. It operates with an input voltage

from 6V up to 36V. It is designed for fast transient

response.

It is available in an innovative industrial high power

density TO263-7EP (10.16 x 13.77 x 4.57mm) package

that enhances thermal performance and allows for hand

or machine soldering.

The VDRM regulators have an integrated protection

circuit that guards against thermal overstress and

electrical damage by using thermal shut-down,

overcurrent, short-circuit, overvoltage and undervoltage

protection.
