MPM54322

16V, 3A, Dual-Output Power Module with I²C Interface

Description

The MPM54322 is a 3A, dual-output power module that integrates a high-efficiency step-down DC/DC converter IC, two inductors, and selected passive components into a single over-molded package. The two outputs can be paralleled for up to 6A of current. The power module features an active current-balancing function that allows equal current sharing for the outputs operating in parallel.

The device offers a dedicated, configurable low-dropout (LDO) regulator with up to 500mA of output current (I_OUT) for ultra-low noise output. Constant on-time (COT) control provides fast transient response and minimizes the required output capacitance.

The on-chip non-volatile memory (NVM) stores and restores device configurations. Operation parameters, as well as timing and protection thresholds are fully configurable via the I²C bus. The MPM54322 offers on-chip current sensing and voltage sensing to accurately monitor the input voltage (V_IN), output voltage (V_OUT), I_OUT, and temperature telemetry via the I²C bus.

The MPM54322 is available in an ultra-thin LGA (5mmx5.5mmx1.85mm) package.
