Description
Demonstration circuit 2438A is an isolated USB datatransceiver featuring the LTM®2894. The demo circuitfeatures an EMI optimized circuit configuration, includingan isolated DC-DC converter, and printed circuit boardlayout. All components for data signaling and isolationare integrated into the LTM2894 using LTC’s isolatorμModule® technology. The demo circuit operates from a supply on VCC and/or VBUS. The DC-DC converter generatesan unregulated isolated output voltage on VCC2 andregulated 5V for USB communication on VBUS2.
