MPM3685

2.7V to 16V, 15A, Step-Down Power Module

概要

The MPM3685 is an easy-to-use, fully integrated, step-down DC/DC power module. The device offers a complete power solution that achieves up to 20A of peak current. It integrates a DC/DC converter, power inductor, and passive components. The MPM3685 can deliver up to 15A of continuous output current (I_OUT) across a wide input voltage (V_IN) supply range, with excellent load and line regulation.

The MPM3685 uses constant-on-time (COT) control to provide fast transient response and ease loop stabilization. The switching frequency (f_SW) can be easily set to 600kHz, 800kHz, or 1000kHz by configuring the MODE pin, allowing f_SW to remain constant regardless of V_IN and the output voltage (V_OUT).

The MPM3685 features a configurable soft-start (SS) time (t_SS) with one capacitor. An open-drain power good (PG) signal indicates whether V_OUT is within the nominal voltage range.

The device has fully integrated, non-latched protection features, including over-current protection (OCP), over-voltage protection (OVP), and over-temperature protection (OTP).

The MPM3685 is available in a compact FCM ECLGA-33 (5mmx5mmx2.76mm) package.

EVM3685-PU-00A 2.7V to 16V, 15A, Step-Down Power Module Evaluation Board

The EVM3685-PU-00A evaluation board is designed to demonstrate the capabilities of the MPM3685, a synchronous, step-down power module with an integrated inductor. The MPM3685 achieves up to 15A of continuous output current (I_OUT) from a 2.7V to 16V input voltage (V_IN) range.

The MPM3685 features a configurable soft-start (SS) time (t_SS) with one capacitor. An open-drain power good (PG) signal indicates whether the output voltage (V_OUT) is within the nominal voltage range.

Full protection features include short-circuit protection (SCP), over-current protection (OCP), under-voltage protection (UVP), and over-temperature protection (OTP).

It is recommended to read the MPM3685 datasheet prior to making any changes to the EVM3685-PU-00A.
