MPM3805A

6V Input, 0.6A Module,

Synchronous, Step-Down Converter

with Integrated Inductor

AEC-Q100 Qualified

DESCRIPTION

FEATURES

The MPM3805A is an automotive grade, step-

down module converter with built-in power

MOSFETs and an inductor. The module’s

integrated inductor simplifies the power system

design and provides easy and efficient use. The

DC/DC module comes in a small surface-



Guaranteed Industrial/Automotive Temp

Wide 2.6V to 6V Operating Input Range

Adjustable Output from 0.6V

Up to 0.6A Peak Output Current

100% Duty Cycle in Dropout

Forced CCM Mode

EN and Power Good for Power Sequencing

Cycle-by-Cycle Over-Current Protection

(OCP)

Short-Circuit Protection (SCP) with Hiccup

Mode

Only Four External Components Required:

Two Ceramic Capacitors, Two FB Divider

Resistors

mounted

QFN-12 (2.5mmx3.0mmx0.9mm)

package and achieves 0.6A of peak output

current from a 2.6V to 6V input voltage range

with excellent load and line regulation. The

output voltage can be regulated as low as 0.6V.

Only FB resistors and input and output

capacitors are needed to complete the design.



The constant-on-time control (COT) scheme

provides fast transient response and eases loop

stabilization. Fault condition protection includes

cycle-by-cycle current limiting and thermal

shutdown.



Available in a QFN-12 (2.5mm x 3.0mm x

0.9mm) Package

Total Solution Size 6mmx3.8mm

Available in AEC-Q100



The MPM3805A is ideal for a wide range of

automotive applications, including small ECUs,

camera modules, telematics, and infotainment

systems.

APPLICATIONS
