TPS258x-Q1 Integrated USB Charging Port Solution

Texas Instruments TPS258x-Q1 Integrated USB Charging Port Solution integrates a monolithic, synchronous, rectified, step-down, switch-mode converter with internal power MOSFETs. It also includes two USB current-limit switches with charging port auto-detection. The TPS2585x-Q1 offers a compact solution that achieves 6.6A of continuous output current with excellent load and line regulation over a wide input supply range. The synchronous buck regulator operates with peak-current mode control and is internally compensated to simplify the design. A resistor on the FREQ pin sets the switching frequency between 200kHz and 3MHz. Operating below 400kHz results in better system efficiency, and operation above 2.1MHz avoids the AM radio bands and allows for a smaller inductor.
