MP2130 EC R NE O EF W M M ER D E E N TO SI D ED G M N P2 S FO 18 R 4 The Future of Analog IC Technology High Efficiency, 3.5A, 6V, 1.2MHz Synchronous Step-Down Converter in an Ultra–Small QFN12 (2x2mm) Package DESCRIPTION FEATURES The MP2130 is a monolithic step-down switch mode converter with built-in internal power MOSFETs. It achieves 3.5A continuous output current from a 2.7V to 6V input voltage with excellent load and line regulation. The MP2130 is ideal for powering portable equipment that runs from a single cell Lithium-Ion (Li+) Battery. The output voltage can be regulated as low as 0.6V.               The Constant-On-time (COT) control scheme provides fast transient response high light-load efficiency and easy loop stabilization. Fault condition protection includes cycle-by-cycle current limit and thermal shutdown. The MP2130 requires a minimum number of readily available standard external components and is available in an ultra-small QFN12 (2x2mm) package. The MP2130 is ideal for a wide range of applications including PDAs, portable instruments, DVD drives, small handhold and battery–powered devices.  Above 95% Peak Efficiency Above 80% Light Load Efficiency. Wide 2.7V to 6V Operating Input Range Output Voltage as Low as 0.6V 100% Duty Cycle in Dropout 3.5A Output Current 50mΩ and 40mΩ Internal Power MOSFET 1.2MHz Frequency EN and Power Good for Power Sequencing Cycle-by-Cycle Over Current Protection Auto Discharge at Power-off Short Circuit Protection with Hiccup Mode Thermal Shutdown Stable with Low ESR Output Ceramic Capacitors Available in a QFN12 (2x2mm) Package APPLICATIONS     Storage Drives Portable/Handheld Devices Wireless/Networking Cards Low Voltage I/O System Power R All MPS parts are lead-free and adhere to the RoHS directive.
