WPMDH1102401 / 171012401
MagI³C Power Module
VDRM - Variable Step Down Regulator Module
6-42V / 1A / 5-24V Output
DESCRIPTION
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 WPMDH1102401 offers high efficiency and
delivers up to 1A of output current. It operates from
6V input voltage up to 42V. 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 on-board protection
circuitry to guard against thermal overstress and
electrical damage featuring thermal shut-down, over-
current, short-circuit, overvoltage and under-voltage
protections.
