Product Description

The MPM3810-AEC1 is an automotive-grade, step-down module converter with built-in power MOSFETs and inductor. The module? integrated inductor simplifies the power system design and provides easy, efficient use. The DC/DC module comes in a small surface-mount QFN-12 (2.5mmx3.0mmx0.9mm) package and achieves 1.2A peak output current from a 2.5V-6V input voltage with excellent load and line regulation. The output voltage is regulated as low as 0.6V. Only FB resistors and input/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 (TSD). The MPM3810-AEC1 is ideal for a wide range of automotive applications, including small ECUs, camera modules, telematics, and infotainment systems.
