MP2158AGQH-P

MP2158A 1A, 6V, 1.5MHz, 17μA IQ, COT Synchronous Step-Down Converter in Ultra-Small 2x1.5mm QFN-8 The Future of Analog IC Technology DESCRIPTION FEATURES The MP2158A is a monolithic step-down, switch-mode converter with built-in internal power MOSFETs. It achieves 1A of continuous output current from a 2.5V to 6V input voltage with excellent load and line regulation. The output voltage can be regulated as low as 0.6V.          The constant-on-time control scheme provides fast transient response and eases loop stabilization. Fault condition protection includes cycle-by-cycle current limiting and thermal shutdown. The MP2158A is available in a small QFN-8 (1.5mmx2mm) package and requires only a minimal number of readily available, standard, external components. The MP2158A is ideal for a wide range of applications, including high-performance DSPs, FPGAs, PDAs, and portable instruments.     Very Low IQ of 17μA Default 1.5MHz Switching Frequency 1.5% VFB Accuracy EN and Power Good for Power Sequencing Wide 2.5V to 6V Operating Input Range Output Adjustable from 0.6V Up to 1A of Output Current 100% Duty Cycle in Dropout 120mΩ and 90mΩ Internal Power MOSFET Switches Cycle-by-Cycle Over-Current Protection Short-Circuit Protection with Hiccup Mode Stable with Low ESR Output Ceramic Capacitors Available in a QFN-8 (1.5mmx2mm) Package APPLICATIONS     Wireless/Networking Cards Portable Instruments Battery-Powered Devices Low Voltage I/O System Power All MPS parts are lead-free, halogen-free, and adhere to the RoHS directive.
