Shown here are some typical applications. On the left, the LTM2884 is used in a powered 2.5W isolated hub port, where the upstream port is connected to the hub microcontroller and the downstream port can supply a USB device with up to 2.5W of power if the LTM2884 is supplied with an external 8.1V to 16.5V input supply. On the right, the LTM2884 is used in a bus powered isolated peripheral device, where the upstream port is deriving power from the 4.4V to 16.5V USB bus and supplies the downstream-connected peripheral with up to 1W of power.
