产品概述
The TPS2500 and TPS2501 provide an integrated solution to meet USB 5-V power requirements from a 1.8-V to 5.25-V input supply. The features include a Hi-Speed USB compliant power output, output switch enable, current limit, and overcurrent fault reporting.The 1.8-V to 5.25-V input can be supplied by sources including dc/dc regulated supplies (e.g., 3.3 V), or batteries such as single-cell Li+ or three-cell NiCd, NiMH, or alkaline.The USB power-switch current limit is programmable via an external resistor from as low as 130 mA to as high as 1400 mA (typical). Two standard USB ports can be supported from a single TPS2500 or TPS2501 at the 1400-mA setting.Additionally, the boost converter output is available as an auxiliary 5.1-V output to power additional loads. The total current supplied by the USB output and the auxiliary cannot exceed 1148 mA at VIN = 3 V.
