DESCRIPTION

The VDMM 171010550 MagI3C MicroModule provides a

fully integrated DC-DC power supply including the

switching regulator with integrated MOSFETs,

compensation, and shielded inductor in one package.

The 171010550 offers high efficiency and delivers up to

1.2A of output current. It operates with an input voltage

from 2.5V to 5.5V and is designed for a small solution size.

The selectable forced PWM or PFM/PWM mode allows for

the choice between high efficiency and low output voltage

ripple at light load.

It is available in an LGA-6EP package (2.5 x 2.5 x 1.2mm).

This module has integrated protection circuitry that guards

against thermal overstress with thermal shutdown and

protects against electrical damage using overcurrent,

short-circuit and undervoltage protections.
