MP2107DQ-LF-Z

MP2107/MP2107A 4A, 6V Synchronous Step-Down Switching Regulator The Future of Analog IC Technology DESCRIPTION FEATURES The MP2107 is an internally compensated 1.5MHz fixed-frequency PWM synchronous step-down regulator. MP2107 operates from a 2.7V to 6V input and generates an output voltage as low as 0.8V.               The MP2107 integrates a 80mΩ high-side switch and a 60mΩ synchronous rectifier for high efficiency without an external Schottky diode. With peak current mode control and internal compensation, the MP2107 based solution delivers a very compact footprint with a minimum component count. The MP2107 is available in a small 3mm x 3mm 10-pin QFN package and the MP2107A is available in an 8-pin SOIC package with an exposed pad. 4A Output Current Input Operation Range: 2.7V to 6V 60mΩ Internal Power MOSFET Switches All Ceramic Capacitor Design Up to 95% Efficiency 1.5MHz Fixed Switching Frequency Adjustable Output from 0.8V to 0.9xVIN Internal Soft-Start Frequency Synchronization Input Power Good Output Cycle-by-Cycle Current Limiting Hiccup Short Circuit Protection Thermal Shutdown 3mm x 3mm 10-pin QFN (MP2107) and 8-pin SOIC (MP2107A) Packages APPLICATIONS     µP/ASIC/DSP/FPGA Core and I/O Supplies Printers and LCD TVs Network and Telecom Equipment Point of Load Regulators “MPS” and “The Future of Analog IC Technology” are Trademarks of Monolithic Power Systems, Inc.
