Description
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 (IOUT) across a wide input voltage (VIN) 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 (fSW) can be easily set to 600kHz, 800kHz, or 1000kHz by configuring the MODE pin, allowing fSW to remain constant regardless of VIN and the output voltage (VOUT).
The MPM3685 features a configurable soft-start (SS) time (tSS) with one capacitor. An open-drain power good (PG) signal indicates whether VOUT 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.
