MPM3809

2.3V to 5.5V Input, 0.6A, PSM Power Module in an Ultra-Small Package

データシート

概要

The MPM3809 is a monolithic, step-down switch-mode converter with built-in, internal power MOSFETs and an inductor. The device achieves 0.6A of continuous output current (I_OUT) from a 2.3V to 5.5V input voltage (V_IN) range, with excellent load and line regulation.

The MPM3809 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 (V_OUT) can be regulated to as low as 0.6V. Only input capacitors, output capacitors, and feedback (FB) resistors are needed to complete the design.

The constant-on-time (COT) control scheme provides fast transient response, high light-load efficiency, and facilitates loop stabilization.

Full protection features include cycle-by-cycle current limiting and thermal shutdown.

The MPM3809 requires a minimal number of readily available, standard external components, and is available in an ultra-small ECLGA-6 (1.5mmx2mmx1mm) package.
