描述The TPS82140 is a 17-V input 2-A step-down converter MicroSiP™ power module optimized for small solution size and high efficiency.The module integrates a synchronous step-down converter and an inductor to simplify design, reduceexternal components and save PCB area. The low profile and compact solution is suitable forautomated assembly by standard surface mount equipment.To maximize efficiency, the converter operates in PWM mode with a nominal switchingfrequency of 2.0MHz and automatically enters Power Save Mode operation at light load currents. InPower Save Mode, the device operates with typically 20-µA quiescent current. Using theDCS-Control™ topology, the device achieves excellent loadtransient performance and accurate output voltage regulation.特性3.0-mm x 2.8-mm x 1.5-mm MicroSiP™Package3.0-V to 17-V Input Range2-A Continuous OutputCurrentDCS-Control™TopologyPower Save Mode for Light Load Efficiency20-µAOperating Quiescent Current0.9-V to 6-V Adjustable Output Voltage 100% Duty Cycle for Lowest DropoutPower GoodOutputProgrammable Soft Startup with TrackingThermalShutdown ProtectionPin to Pin compatible withTPS82130 andTPS82150–40°C to 125°COperating Temperature RangeCreate a Custom Design usingthe TPS82140 with theWEBENCH®Power DesignerAll trademarks are the property of their respective owners.
