MPM3683-10

2.7V to 16V, 10A, Step-Down Power Module

Description

The MPM3683-10 is an easy-to-use, fully integrated step-down DC/DC power module that integrates a DC/DC converter, power inductor, and passive components. It can achieve up to 10A of continuous output current (I_OUT) across a wide input voltage (V_IN) range, with excellent load and line regulation.

Constant-on-time (COT) control provides fast transient response and eases loop stabilization. The selectable switching frequency (f_SW) can be set to 600kHz, 800kHz, or 1000kHz via the MODE pin. This allows the MPM3683-10 to maintain a constant f_SW, regardless of V_IN and the output voltage (V_OUT).

The MPM3683-10 features a configurable soft-start time (t_SS) and a power good (PG) signal that indicates whether V_OUT is within the nominal voltage range. Fully integrated, non-latch protection features include over-current protection (OCP), over-voltage protection (OVP), and thermal shutdown.

The MPM3683-10 is available in a compact LGA-29 (7mmx7mmx4.4mm) package.
