17 The MPQ8785 is a fully integrated, PMBus-compatible, high-frequency, synchronous
18 buck converter. The MPQ8785 offers a very compact solution that achieves up to
19 40A output current per phase, with excellent load and line regulation over a
20 wide input supply range. The MPQ8785 operates at high efficiency over a wide
21 output current load range.
23 The PMBus interface provides converter configurations and key parameters
26 The MPQ8785 adopts MPS's proprietary multi-phase digital constant-on-time (MCOT)
27 control, which provides fast transient response and eases loop stabilization.
28 The MCOT scheme also allows multiple MPQ8785 devices to be connected in parallel
29 with excellent current sharing and phase interleaving for high-current
32 Fully integrated protection features include over-current protection (OCP),
33 over-voltage protection (OVP), under-voltage protection (UVP), and
34 over-temperature protection (OTP).
36 The MPQ8785 requires a minimal number of readily available, standard external
37 components, and is available in a TLGA (5mmx6mm) package.
