MP2147GD-Z Monolithic Power Systems

MP2147 5.5V, 4A, 1.2MHz, High-Efficiency, 40A I Q Constant On-Time Synchronous, Step-Down Switcher The Future of Analog IC Technology DESCRIPTION FEATURES The MP2147 is a monolithic, step-down, switch- Up to 4A Output Current mode converter with internal power MOSFETs. It Wide 2.8V-to-5.5V Operating Input Range can achieve up to 4A continuous output current 22m and 14m Internal Power MOSFETs from a 2.8V-to-5.5V input voltage with excellent 40A Quiescent Current load and line regulation. The output voltage can 1.2MHz Fixed Switching Frequency be regulated to as low as 0.6V. 1% Feedback Accuracy External Mode Control Constant-on-time control provides a fast transient response and eases loop stabilization. Fault External VCON Control condition protections include cycle-by-cycle Adjustable Output from 0.6V current limiting and thermal shutdown. 1.5ms Internal SS Time with Pre-Bias Startup Cycle-by-Cycle Over Current Protection The MP2147 is available in a small QFN23mm Short Circuit Protection with Hiccup Mode package and requires only a minimal number of Stable with Low-ESR Output Ceramic readily-available, standard, external components. Capacitors The MP2147 is ideal for a wide range of Thermal Shutdown applications, including storage (SSD, HDD), high- Available in a 2mm3mm QFN Package performance DSPs, FPGAs, and distributed Output Discharge Function power systems. APPLICATIONS Storage (SSD, HDD) Portable Instruments Battery-Powered Devices All MPS parts are lead-free, halogen free, and adhere to the RoHS directive.
