DESCRIPTION

The VDRM series of the MagI³C Power Module family

provides a fully integrated DC-DC power supply including

the buck switching regulator, inductor, input and output

capacitors in a package, allowing a minimum external

components count solution, quick time to market and

ease of use.

The 171031801 family offers high efficiency and delivers

up to 3A of output current. It operates from 4V input

voltage up to 18V. It is designed for fast transient

response.

It is available in an innovative industrial high power

density LGA-16EP (9 x 9 x 3mm) package that enhances

thermal performance.

The VDRM regulators have an integrated protection

circuit that guards against thermal overstress and

electrical damage by using thermal shut-down,

overcurrent, short-circuit, and undervoltage protection.
