Product Summary
The TPS2145IPWP is a LDO and dual switch. The TPS2145IPWP incorporates two power distribution switches and an LDO in one small package, providing a USB bus-powered hub power management solution that saves up to 60% in board space over typical implementations. The TPS2145IPWP meets USB 2.0 bus-powered hub requirements. An integrated LDO regulates the 5-V bus power down to 3.3 V for the USB controller. The two MOSFET switches provide power to the downstream ports. The applications of the TPS2145IPWP include USB Bus-Powered Hubs, Keyboards, Monitors, Hub Boxes.
