The EVQ8785-MJ-1PHASE-01A 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 voltage (V_IN) 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 device adopts MPS’s proprietary, digital, multi-phase constant-on-time (MCOT) control to provide fast transient response and ease loop stabilization. The MCOT scheme also allows 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-37 (5mmx6mm) package.
