MP9161A Datasheet | Monolithic Power Systems

DESCRIPTION The MP9161A is a monolithic, step-down, switch-mode converter with built-in internal power MOSFETs. It achieves a 2A continuous output current from a 2.5V to 6V input voltage range with excellent load and line regulation. The output voltage is regulated as low as 0.6V. 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 MP9161A is available in a small TSOT23-8 package and requires a minimum number of readily available, standard, external ponents. The MP9161A is ideal for a wide range of applications including high performance DSPs, FPGAs, PDAs, and portable instruments. 2A, 6V, 1.5MHz, 17μA IQ, COT Synchronous Step-Down Converter in 8-pin TSOT23 FEATURES - Very Low IQ: 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 2A Output Current - 100% Duty Cycle in Dropout - 110mΩ and 60mΩ 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 Ro HS directive.
