DESCRIPTION

The MPM3810A 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

MPM3810A achieves 1.2A of peak output

current from a 2.6V to 6V input voltage range

with excellent load and line regulation. The

output voltage is regulated as low as 0.6V. Only

FB resistors and input/output capacitors are

required to complete the design.

The constant-on-time control (COT) scheme

provides fast transient response and eases loop

stabilization. Full protection features include

cycle-by-cycle current limiting and thermal

shutdown.

The MPM3810A is ideal for a wide range of

automotive applications including small ECUs,

camera modules, telematics, and infotainment

systems.

The MPM3810A is available in a small surface-

mounted

QFN-12

(2.5mmx3.0mmx0.9mm)

package.
