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 output current (IOUT) across a wide input 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 operating frequency can be easily set to 600kHz, 800kHz, or 1000kHz with the MODE configuration, allowing the MPM3685’s frequency to remain constant regardless of the input voltage (VIN) and output voltage (VOUT).
The MPM3685 features a configurable soft-start time (tSS) with a capacitor. An open-drain power good (PG) signal indicates whether VOUT is within the nominal voltage range.
The MPM3685 provides 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.
