The MP8620 is a fully integrated step-down converter with internal power MOSFETs. It achieves 25A continuous output current over a wide input supply range with excellent load and line regulation. The MP8620 can be configured and optimized as a single phase or a multi-phase solution to support high current (50A-100A) applications. This provides the flexibility and at the same time meets the efficiency requirement with less components. Average current mode control scheme is employed in the MP8620. The device operates reliably even with low duty cycle and noisy environment. Fault condition protection include cycle¬-by¬-cycle current limit, thermal shutdown, output short-circuit, output under voltage and output over voltage protection. The MP8620 requires a minimum number of readily available standard external components and is available in a 6mm x 6mm flip-chip QFN package. The MP8620 is suitable for a wide range of space-constraint applications, including point of load regulation for FPGAs, ASICs, DDR memory power, and power systems for networking and data centers.
