MP8774 12A, Wide Input 3V-18V, 700kHz Synchronous Step-down Converter with PG and External Soft Start in 3x3mm QFN package DESCRIPTION FEATURES The MP8774 is a fully integrated high-frequency, Output Adjustable from 0.6V synchronous, rectified, step-down, switch-mode Wide 3V to 18V Operating Input Range converter with internal power MOSFETs. The 12A Output Current MP8874 offers a very compact solution that 16m/5.5m Low R Internal Power DS(ON) achieves 12A of continuous output current with MOSFETs excellent load and line regulation over a wide 100 A Quiescent Current input range. The MP8774 uses synchronous High-Efficiency Synchronous Mode mode operation for higher efficiency over the Operation 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 MP8774 requires a minimal number of readily available, standard, external APPLICATIONS components and is available in a space-saving Security Cameras QFN-16 (3mmx3mm) package.
