MP2158 1A, 6V, 1.5MHz, 17 A I , COT Q Synchronous Step Down Switcher In Ultra-small 2x1.5mm QFN The Future of Analog IC Technology DESCRIPTION FEATURES The MP2158 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 1A continuous output EN and Power Good for Power Sequencing current from a 2.5V to 6V input voltage with Ultra-small 2.0x1.5mm 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 1A 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 118m and 88m 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 MP2158 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 MP2158 is ideal for a wide range of Wireless/Networking Cards applications including High Performance DSPs, Portable Instruments FPGAs, PDAs, and portable instruments.
