MP2152GTF-Z

MP2152 The Future of Analog IC Technology 5.5V, 2A, Sync Step-Down Converter with 25μA IQ and Output Discharge in QFN and SOT563 Packages DESCRIPTION FEATURES The MP2152 is a monolithic, step-down, switchmode converter with built-in, internal power MOSFETs. The MP2152 achieves 2A of continuous output current from a 2.5V to 5.5V input voltage with excellent load and line regulation. The output voltage can be regulated as low as 0.6V.         The constant-on-time (COT) control scheme provides fast transient response and eases loop stabilization. Fault protections include cycle-bycycle current limiting and thermal shutdown. The MP2152 is ideal for a wide range of applications including high performance DSPs, wireless power, portable and mobile devices, and other low-power systems. The MP2152 requires a minimal number of readily available, standard, external components and is available in ultra-small SOT563 or 1.2mmx1.6mm UTQFN packages.       Low IQ: 25μA 1.1MHz Switching Frequency EN for Power Sequencing 1% FB Accuracy Wide 2.5V to 5.5V Operating Input Range Output Adjustable from 0.6V Up to 2A Output Current 75mΩ and 45mΩ Internal Power MOSFET Switches 100% Duty On Output Discharge VOUT Over-Voltage Protection (OVP) Short-Circuit Protection (SCP) with Hiccup Mode Power Good Only for Fixed Output Version Available in SOT563 or UTQFN (1.2mmx1.6mm) Packages APPLICATIONS       Wireless/Networking Cards Portable Instruments Battery-Powered Devices Low-Voltage I/O System Power Multi-Function Printers Solid-State Drives All MPS parts are lead-free, halogen-free, and adhere to the RoHS directive.
