MP8770 17V, 8A, 700kHz, High-Efficiency, Synchronous, Step-Down Converter DESCRIPTION FEATURES The MP8770 is a fully integrated, high- Wide 3V to 17V Operating Input Range frequency, synchronous, rectified, step-down, 8A Output Current switch-mode converter with internal power 22m/10m Low R Internal Power DS(ON) MOSFETs. The MP8770 offers a very compact MOSFETs solution that achieves 8A 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 MP8770 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. EN and Power Good for Power Sequencing Over-Current Protection (OCP) and Hiccup Full protection features include short-circuit Thermal Shutdown protection (SCP), over-current protection (OCP), Available in a QFN-16 (3mmx3mm) under-voltage protection (UVP), and thermal Package shutdown. The MP8770 requires a minimal number of APPLICATIONS readily available, standard, external Security Cameras components and is available in a space-saving Portable Devices, XDSL Devices QFN-16 (3mmx3mm) package.
