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-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.
The MPM3805A is ideal for a wide range of automotive applications, including small ECUs, camera modules, telematics, and infotainment systems.
