MP2159A 1 A, 6 V, 1.5 MHz, Low IQ, COT Synchronous Step-Down Converter in 8-pin TSOT23 The Future of Analog IC Technology FEATURES DESCRIPTION The MP2159A is a monolithic step-down, switchmode converter with built-in power MOSFETs. It achieves a 1 A continuous output current from a 2.5 V to 6 V input voltage range with excellent load and line regulation. The output voltage can be regulated as low as 0.6 V. The constant-on-time (COT) control scheme provides fast transient response and eases loop stabilization. Fault condition protection includes cycle-by-cycle current limiting and thermal shutdown. The MP2159A is available in a small TSOT23-8 package and requires a minimum number of readily available, standard, external components. The MP2159A is ideal for a wide range of applications including high-performance DSPs, FPGAs, PDAs, and portable instruments.              Very Low IQ: 17 μA Default 1.5 MHz Switching Frequency 1.5% VFB Accuracy EN and Power Good for Power Sequencing Wide 2.5 V to 6 V Operating Input Range Output Adjustable from 0.6 V Up to 1 A Output Current 100% Duty Cycle in Dropout 120 mΩ and 90 mΩ 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 TSOT23-8 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.
