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