    Description

    The TPS2148 incorporates two power distribution switches and an LDO in one small package, providing a USB peripheral power management solution that saves up to 60% in board space over typical implementations.

    The TPS2148 meets USB 2.0 bus-powered peripheral requirements. An integrated LDO regulates the 5-V bus power down to 3.3 V for the USB controller, and a MOSFET switch that is internally connected to the output of the LDO simplifies meeting the suspend and enumeration current requirements imposed by the USB specification.

    A second switch is available to support a downstream port, stage power to a second voltage regulator, or disable power to selected circuitry in power-save modes.

    Each power-distribution switch is capable of supplying 200 mA of continuous current, and the independent logic enables are compatible with 5-V logic and 3-V logic.
