MPM3683-20

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

Datasheet

Description

The MPM3683-20 is an easy-to-use, fully integrated, step-down DC/DC power module. The MPM3683-20 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 MPM3683-20 can deliver the output current (I_OUT) across a wide input voltage (V_IN) supply range, with excellent load and line regulation.

The MPM3683-20 uses constant-on-time (COT) control to provide fast transient response and ease loop stabilization. The operating switching frequency (f_SW) can be set to 600kHz, 800kHz, or 1000kHz with the MODE pin. This allows f_SW to remain constant, regardless of V_IN or the output voltage (V_OUT).

The MPM3683-20 features a configurable soft start time (t_SS) with one capacitor. An open drain power good (PG) signal indicates whether V_OUT is within the nominal voltage range.

The MPM3683-20 has fully integrated, non-latch protection features including over-current protection (OCP), over-voltage protection (OVP), and over-temperature protection (OTP).

The MPM3683-20 is available in a compact FCM LGA-29 (7mmx7mmx4.4mm) package.
