Descrição geral do produto

The TPS2500DRCT is an USB Power Switch provides an integrated solution to meet USB 5V power requirements from a 1.8 to 5.25V input supply. The features include a Hi-Speed USB compliant power output, output switch enable, current limit and overcurrent fault reporting. The 1.8 to 5.25V input can be supplied by sources including DC/DC regulated supplies (e.g., 3.3V) 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 130mA to as high as 1400mA (typical). Two standard USB ports can be supported from a single TPS2500 at the 1400mA setting. Additionally, the boost converter output is available as an auxiliary 5.1V output to power additional loads. The total current supplied by the USB output and the auxiliary cannot exceed 1148mA at VIN = 3V.
  • Integrated synchronous boost converter and USB current-limit power switch
  • Light-load, high-efficiency Eco-mode™ control scheme
  • Accurate 20% current limit at 1.4A setting
  • Powers up to two standard USB ports
