MP2162GQH-Z Monolithic Power Systems

MP2162 2A, 6V, 1.5MHz, 17 A I , COT Q Synchronous Step Dwon Switcher In Ultra-small 2x1.5mm QFN The Future of Analog IC Technology DESCRIPTION FEATURES The MP2162 is a monolithic step-down switch Very Low I : 17 A Q mode converter with built-in internal power Default 1.5MHz Switching Frequency MOSFETs. It achieves 2A continuous output EN and Power Good for Power Sequencing current from a 2.5V to 6V input voltage with Ultra-small 2x1.5mm QFN8 Package excellent load and line regulation. The output Wide 2.5V to 6V Operating Input Range voltage can be regulated as low as 0.6V. Output Adjustable from 0.6V Up to 2A Output Current The Constant-On-Time control scheme provides fast transient response and eases loop 100% Duty Cycle in Dropout stabilization. Fault condition protection includes 100m and 60m Internal Power MOSFET Switches cycle-by-cycle current limiting and thermal shutdown. Cycle-by-Cycle Over Current Protection Short Circuit Protect with Hiccup Mode The MP2162 is available in the small QFN8 Stable with Low ESR Output Ceramic 2.0x1.5mm package and requires a minimum Capacitors number of readily available standard external components. APPLICATIONS The MP2162 is ideal for a wide range of Wireless/Networking Cards applications including High Performance DSPs, Portable Instruments FPGAs, PDAs, and portable instruments.
