MP8772 12A, 17V, 700kHz Synchronous Step-down Converter with PG and External Soft Start in 3x3mm QFN package DESCRIPTION FEATURES The MP8772 is a fully integrated, high- Output Adjustable from 0.6V frequency, synchronous, rectified, step-down, Wide 3V to 17V Operating Input Range switch-mode converter with internal power 12A Output Current MOSFETs. The MP8772 offers a very compact 16m/5.5m Low R Internal Power DS(ON) solution that achieves 12A of continuous output MOSFETs current with excellent load and line regulation 100 A Quiescent Current over a wide input range. The MP8772 uses High-Efficiency Synchronous Mode synchronous mode operation for higher Operation efficiency over the output current load range. Pre-Biased Start-Up Fixed 700kHz Switching Frequency Constant-on-time (COT) control operation 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 MP8772 requires a minimal number of readily available, standard, external APPLICATIONS components and is available in a space-saving Security Cameras QFN-16 (3mmx3mm) package.
