MP8771GQ-P Monolithic Power Systems

MP8771 18V, 10A, 700kHz, High-Efficiency, Synchronous, Step-Down Converter DESCRIPTION FEATURES The MP8771 is a fully integrated, high- Wide 3V to 18V Operating Input Range frequency, synchronous, rectified, step-down, 10A Output Current switch-mode converter with internal power 17m/8m Low R Internal Power DS(ON) MOSFETs. The MP8771 offers a very compact MOSFETs solution that achieves 10A of continuous output 100 A Quiescent Current current with excellent load and line regulation Output Adjustable from 0.6V over a wide input range. The MP8771 uses High-Efficiency Synchronous Mode synchronous mode operation for higher Operation efficiency over the output current load range. Pre-Biased Start-Up Constant-on-time (COT) control operation Fixed 700kHz Switching Frequency provides very fast transient response, easy loop External Programmable Soft Start-Up Time design, and very tight output regulation. Enable (EN) and Power Good (PG) for Power Sequencing Full protection features include short-circuit Over-Current Protection (OCP) and Hiccup protection (SCP), over-current protection (OCP), Thermal Shutdown under-voltage protection (UVP), and thermal Available in a QFN-16 (3mmx3mm) shutdown. Package The MP8771 requires a minimal number of The MPL-AY1265 Inductor Series Matches readily available, standard, external Best Performance components and is available in a space-saving QFN-16 (3mmx3mm) package.
