Description
The MPM3812 is a monolithic, step-down switch-mode converter with built-in, internal power MOSFETs and an inductor. The MPM3812 achieves up to 1A of continuous output current (IOUT) from a 2.3V to 5.5V input voltage (VIN), with excellent load and line regulation. The MPM3812 is ideal for a wide range of applications, including high-performance digital signal processors (DSPs), wireless power, portable and mobile devices, and other low-power systems. The output voltage (VOUT) can be regulated to as low as 0.6V. Only input capacitors, output capacitors, and feedback (FB) resistors are required to complete the design.
The constant-on-time (COT) control scheme provides fast transient response, high light-load efficiency, and easy loop stabilization.
Full protection features include cycle-by-cycle current limiting and thermal shutdown.
The MPM3812 requires a minimal number of readily available, standard external components, and it is available in an ultra-small ECLGA-6 (1.5mmx2mmx1mm) package.
