DESCRIPTION

The MPM3683-10 is an easy-to-use, fully integrated, DC/DC step-down power module,

with 10A of continuous output current (IOUT). The MPM3683-10 integrates a DC/DC converter, power inductor, and passive components. It can deliver IOUT across a wide input voltage (VIN) supply range, with excellent load and line regulation.

The constant-on-time (COT) control scheme provides fast transient response and eases loop stabilization. The operating switching frequency fSW) can be easily set to 600kHz, 800kHz, or 1000kHz using the MODE configuration. This allows the MPM3683-10’s fSW to remain constant regardless of VIN and the output voltage (VOUT).

The MPM3683-10 features a configurable softstart time (tSS) with a capacitor. An open-drain power good (PG) signal indicates whether VOUT is within the nominal voltage range.

Fully integrated, non-latched protections include over-current protection (OCP), over-voltage protection (OVP), and over-temperature protection (OTP).

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