PN-DESIGNKIT-57 PortNote® Solution and Design Kit

Bourns offers its USB power delivery protection PortNote solution and design kit. The USB power delivery specification enables data and up to 100 W of power simultaneously on one USB cable. This PortNote solution illustrates how a polymer PTC (Bourns Model MF-LSMF300/24X) can protect the DC bus during short circuit testing as recommended by USB 3.1 Section 11.4.1.1.1. The high-speed data lines for negotiating power, as well as the USB bus itself, require overvoltage protectors with low capacitance which are provided by Bourns 5 V and 3.3 V 4-channel TVS diode arrays (Bourns Model CDDFN10-0524P and CDDFN10-3324P). The DC link bus requires a step-down or step-up converter with a high current soft saturation power inductor such as the Bourns Model SRP6540-100M power inductor (7.2 mm x 6.5 mm x 4.0 mm).
