MP8796BGVT-0000-Z

MP8796B is a fully integrated, PMBus compatible, high-frequency, synchronous buck converter. The MP8796B 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 MP8796B operates at high efficiency over a wide output current load range. The PMBus interface provides converter configurations and key parameter monitoring. The MP8796B adopts MPS’s proprietary, multiphase constant-on-time (MCOT) control, which provides fast transient response and eases loop stabilization. The MCOT control scheme also allows multiple MP8796B devices to be connected in parallel with excellent current sharing and phase interleaving for high-current applications. Fully integrated protection features include OCP, OVP, UVP and OTP. The MP8796B requires a minimal number of readily available, standard external components and is available in a TQFN-25 (4mmx5mm) package.
