MP8620 25A, 16V, Fully Integrated Synchronous Buck The Future of Analog IC Technology FEATURES DESCRIPTION Supports Multi-phase Configuration up to The MP8620 is a fully integrated step-down 100A converter with internal power MOSFETs. It Wide 6V to 16V Operating Input Range achieves 25A continuous output current over a 25A Output Current wide input supply range with excellent load and line regulation. The MP8620 can be configured 3m/12m Internal Power MOSFET and optimized as a single phase or a multi- Switches Deliver up to 95% Efficiency phase solution to support high current (50A- Synch Output to Drive Another Regulator in 100A) applications. This provides the flexibility 90o, 120o,180o Phase-Shift Operation and at the same time meets the efficiency Synch from 300kHz to 900kHz External requirement with less components. Clock Default 600kHz Frequency, Programmable Average current mode control scheme is from 300kHz to 1.5MHz. employed in the MP8620. The device operates Feedback Voltage Accuracy: 1.0% reliably even with low duty cycle and noisy Programmable Soft-Start environment. Startup Tracking Fault condition protection include cycle-by-cycle EN and Power Good for Power Sequencing current limit, thermal shutdown, output short- Cycle-by-Cycle Over Current Protection, circuit, output under voltage and output over SCP, OCP, OVP, UVP and Thermal voltage protection. Shutdown The MP8620 requires a minimum number of Output Adjustable from 0.8V readily available standard external components Stable with Low ESR Output Ceramic and is available in a 6x6mm QFN package. Capacitors Available in a 6x6mm QFN Package The MP8620 is suitable for a wide range of space-constraint applications, including point of APPLICATIONS load regulation for FPGAs, ASICs, DDR Distributed Power Systems memory power, and power systems for Pre-Regulator for Linear Regulators networking and data centers.
