MP8765GQ-Z Monolithic Power Systems

MP8765 24V, 6A High Efficiency Synchronous Step-down Converter The Future of Analog IC Technology DESCRIPTION FEATURES The MP8765 is a fully integrated high frequency Wide 5V to 24V Operating Input Range synchronous rectified step-down switch mode 6A Continuous Output Current converter. It offers very compact solutions to PFM/PWM Mode Selectable achieve 6A continuous output current over a Low R (ON) Internal Power MOSFETs DS wide input supply range with excellent load and Proprietary Switching Loss Reduction line regulation. The MP8765 operates at high Technique efficiency over a wide output current load range. 1% Reference Voltage 7ms Internal Soft Start Constant-On-Time (COT) control mode provides fast transient response and eases loop Output Discharge stabilization. 500kHz Switching Frequency Hiccup OCP Protection and Thermal Under voltage lockout is internally set as 4.6 V, Shutdown An open drain power good signal indicates the Auto Retry OVP Protection output is within its nominal voltage range. Output Adjustable from 0.604V to 5.5V Full protection features include OCP and thermal APPLICATIONS shut down. Laptop Computer The converter requires minimum number of Tablet PC external components and is available in QFN16 (3mmx3mm) package.
