MP2276 8A, 2.7-16V Input, High-Efficiency Synchronous Step-down Converter with Programmable Current Limit and Soft Start Time Selectable Frequency and Mode of Operation The Future of Analog IC Technology DESCRIPTION FEATURES The MP2276 is a fully integrated, high- Wide 2.7V to 16V Input Voltage Range frequency, synchronous, rectified, step-down, 8A Continuous Output Current switch-mode converter. It offers a very compact Integrated Power 24m/10m Low R DS(ON) solution that achieves up to 8A of continuous MOSFETs output current with excellent load and line Adaptive Constant-On-Time (COT) for regulation over a wide input supply range. The Ultrafast Transient Response MP2276 operates at high efficiency over a wide Stable with Zero ESR Output Capacitor output current load range. Programmable Current Limit Selectable Forced CCM or Pulse-Skip The MP2276 uses constant-on-time (COT) Operation at Light Load control for fast transient response and eased loop stabilization. Excellent Load Regulation Programmable Soft-Start Time from 1.7ms Output voltage start-up is controlled by an Pre-Bias Start-Up internal 1.7ms timer, which can be increased by Selectable 600kHz, 1100kHz, or 2000kHz adding a capacitor on SS/TRK. An open-drain Switching Frequency power good (PG) signal indicates when the Hiccup Over-Current Protection (OCP) output is within its nominal voltage range. Auto-Retry Over-Voltage Protection (OVP) Full protection features include over-current and Thermal Shutdown protection (OCP), over-voltage protection Output Adjustable from 0.8V (OVP), under-voltage protection (UVP), and Available in a QFN-14 (2mmx3mm) over-temperature protection (OTP). Package The MP2276 requires a minimal number of APPLICATIONS readily available, standard, external components and is available in a QFN-14 Digital Set-Top Boxes (2mmx3mm) package.
