The EVQ8785-MJ-1PHASE-00A is an evaluation board designed to demonstrate the capabilities of the MPQ8785, a fully integrated, PMBus-compatible, high-frequency, synchronous buck converter. The MPQ8785 offers a very compact solution that achieves up to 40A of output current (I_OUT) per phase, with excellent load and line regulation across a wide input supply range.

The MPQ8785 achieves high efficiency across a wide I_OUT load range. The PMBus interface provides the converter configurations and monitors key parameters.

The MPQ8785 adopts MPS’s proprietary, digital multi-phase constant-on-time (MCOT) control to facilitate loop stabilization. The MCOT scheme also provides fast transient response and eases looping multiple MPQ8785 devices to be connected in parallel, with excellent current sharing and phase interleaving for high-current applications.

Fully integrated protection features include over-current protection (OCP), over-voltage protection (OVP), under-voltage protection (UVP), and over-temperature protection (OTP).

The MPQ8785 requires a minimal number of readily available, standard external components, and is available in a TLGA (5mmx6mm) package.
