MagI³C Power Module Product Family
VDRM - Variable Step Down Regulator Module
DESCRIPTION
The VDRM series of the MagI³C Power Modules
Family comprise a fully integrated current mode
DC/DC power supply with both the switching power
stage, control circuitry and passive all in one package
These devices also feature built-in compensation
circuitry and a soft-start feature for a smooth, safe
power up. The 7 PIN PFM is an industrial high power
density package with a low profile and a small outline.
The VDRM series offers high efficiency and delivers up
to 1.5A of output current with accurate regulated
output voltages. It operates from input voltage 6V to
42V.
They are available in an innovative package that
enhances thermal performance and allows for hand or
machine soldering.
The VDRM regulators also have on-board protection
circuitry to guard against thermal and electrical
damage. Thermal shut-down, over-current,
overvoltage and under-voltage protections safeguard
the regulator and include a short-circuit protection.
