MPQ2171GJ-AEC1-P

MPQ2171 The Future of Analog IC Technology 5.5V, 1A, 2.6MHz, Synchronous, Step-Down Converter AEC-Q100 Qualified DESCRIPTION FEATURES The MPQ2171 is a monolithic, step-down, switch-mode converter with integrated, internal, power MOSFETs. The MPQ2171 can achieve up to 1A 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 MPQ2171 is ideal for a wide range of applications, including automotive infotainment, clusters, telematics, and portable instruments. The MPQ2171 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 1A Output Current 90mΩ and 50mΩ 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 Available in AEC-Q100 Grade 1 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.
