MP2172GJ-Z

MP2172 5.5V, 2A, 2.6MHz, Synchronous, Step-Down Switcher The Future of Analog IC Technology DESCRIPTION FEATURES The MP2172 is a monolithic, step-down, switchmode converter with integrated, internal, power MOSFETs. The MP2172 can achieve up to 2A of continuous output current from a 2.5V to 5.5V input voltage with excellent load and line regulation. The output voltage can be regulated as low as 0.6V.      Constant-on-time (COT) control provides fast transient response and eases loop stabilization. Full protection features include cycle-by-cycle current limiting and thermal shutdown. The MP2172 is ideal for a wide range of applications, including automotive infotainment, clusters, telematics, and portable instruments. The MP2172 requires only a minimal number of readily available, standard, external components and is available in a small TSOT23-8 package.        Wide 2.5V to 5.5V Operating Input Range Output Voltage as Low as 0.6V 100% Duty Cycle in Dropout Up to 2A Output Current 80mΩ and 45mΩ Internal Power MOSFET Switches Default 2.6MHz Switching Frequency with 3.3V Input and 1.8V Output EN and Power Good for Power Sequencing Cycle-by-Cycle Over-Current Protection (OCP) Auto Discharge at Power-Off Short-Circuit Protection (SCP) with Hiccup Mode Stable with Low ESR Output Ceramic Capacitors Available in a TSOT23-8 Package APPLICATIONS      Automotive Infotainment Automotive Clusters Automotive Telematics Low-Voltage I/O System Power Handheld/Battery-Powered Systems All MPS parts are lead-free, halogen-free, and adhere to the RoHS directive.
