USB is a four-wire interface — two for differential signaling and two for power.
The LTM2884 from Linear Technology includes two USB transceivers, each facing the outside pins. It also has an integrated, regulated 2.5 watt flyback DC-to-DC converter, complete with an isolation transformer, output diodes and capacitors, plus 3.3V LDO regulators that power each USB transceiver. The LTM2884 is a robust USB transceiver solution that thrives even in harsh environments.
