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

(IOUT) across a wide input voltage (VIN) 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 (fSW) can be

set to 600kHz, 800kHz, or 1000kHz with the

MODE pin. This allows fSW to remain constant,

regardless of VIN or the output voltage (VOUT).

The MPM3683-20 features a configurable softstart

time (tSS) with one capacitor. An opendrain

power good (PG) signal indicates whether

VOUT is within the nominal voltage range.

The MPM3683-20 has fully integrated, nonlatch

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.
