MPM3805B

6V, 0.6A, Synchronous Step-Down

Module Converter with Integrated

Inductor, AEC-Q100 Qualified

DESCRIPTION

FEATURES

The MPM3805B is an automotive-grade, step-

down module converter with a built-in inductor

and power MOSFETs. It achieves 0.6A of peak

output current from a 2.5V to 6V input voltage

range, with excellent load and line regulation.

The output voltage is fixed to 1.2V, so the device

only requires input and output capacitors to

complete the design.



Guaranteed Industrial/Automotive Temp

Wide 2.5V to 6V Operating Input Range

Fixed 1.2V Output

Up to 0.6A Peak Output Current

100% Duty Cycle in Dropout Mode

Forced Continuous Conduction Mode (CCM)

EN and Power Good for Power Sequencing

Cycle-by-Cycle Over-Current Protection

Short-Circuit Protection with Hiccup Mode

Only Requires Two External Ceramic

Capacitors

The device’s integrated inductor simplifies the

power system design and provides easy, efficient

use. Constant-on-time (COT) control provides

fast transient response and eases loop

stabilization. Fault protections include cycle-by-

cycle current limiting and thermal shutdown

(TSD).

Total Solution Size of 6mmx3.8mm

Available in a QFN-12

(2.5mmx3.0mmx0.9mm) Package



Available in AEC-Q100 Grade 1

The MPM3805B is ideal for a wide range of

automotive applications, including small ECUs,

camera modules, telematics, and infotainment

systems. It is available in a small, surface-
