MP2117DN-LF-Z

MP2117 1.25MHz, 2.2A Synchronous Step-Down Switcher DESCRIPTION FEATURES The MP2117 is an internally compensated 2.2A synchronous step-down switcher. The operating frequency is internally set at 1.25MHz. MP2117 is ideal for powering portable equipment that runs from a single cell Lithium-Ion (Li+) Battery. The MP2117 can provide up to 2.2A continuous load current from a 2.5V to 6V input voltage. The output voltage can be regulated as low as 0.6V. 100% duty cycle provides low dropout operation that extends operating time in batteryoperated systems. • • • • • • • • • • • • • • The MP2117 features an integrated high-side switch and synchronous rectifier for high efficiency. With peak current mode control and internal compensation, the MP2117 can be stabilized with ceramic capacitors and small inductors. Fault condition protection includes cycle-by-cycle current limiting and thermal shutdown. MP2117 is available in the small 10-pin 3mmx3mm QFN and SOIC-8 packages. 2.2A Output Current 2.5V to 6V Input Range VIN Internal Power MOSFET Switches Low Dropout Operation: 100% Duty Cycle Up to 90% Efficiency Stable with Ceramic Output Capacitors 1μA Shutdown Current 1.25MHz Switching Frequency Thermal Shutdown Cycle-by-Cycle Over Current Protection Output Short Circuit Protection Internal Soft-start Power On Reset Output Available in 10-Pin QFN (3mmx3mm) and 8-pin SOIC Packages APPLICATIONS • • • • DVD+/-RW Drives LCD TV PDAs Portable Instruments “MPS” and “The Future of Analog IC Technology” are Registered Trademarks of Monolithic Power Systems, Inc.
