MPQ8785

16V, 40A, Scalable, Digital, Synchronous Step-Down Converter with PMBus

Description

The MPQ8785 is a fully integrated, PMBus-compliant, high-frequency, synchronous buck converter. The device 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 voltage (V_IN) supply range. The MPQ8785 operates at a high efficiency across the wide I_OUT load range. The PMBus interface provides converter configurations and monitors key parameters.

The MPQ8785 adopts MPS’s proprietary, digital, multi-phase constant-on-time (MCOT) control, which provides fast transient response and facilitates 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 it is available in a TLGA-37 (5mmx6mm) package.
