The MPQ8645P is a fully integrated, PMBusTM-compatible, high-frequency, synchronous buck converter. The MPQ8645P offers a very compact solution that achieves up to 30A of output current per-phase with excellent load and line regulation over a wide input supply range. The MPQ8645P operates at high efficiency over a wide output current load range.
The PMBusTM interface provides converter configurations and key parameter monitoring.
The MPQ8645P adopts MPS’s proprietary multi-phase constant-on-time (MCOT) control, which provides fast transient response and eases loop stabilization. The MCOT scheme also allows multiple MPQ8645P 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 MPQ8645P requires a minimal number of readily available, standard, external components and is available in a TQFN-25 (4mmx5mm) package.
