Using the TPS40170 PWM Buck Controller, this power management reference design provides a regulated 5V to power 2 USB ports at 2.1A each (total 4.2A) in a small form-factor. The design has been optimized for a nominal 12V input and accepts 8-60V with TPS40170.
Form factor complies to UL 2089 and ANSI/SAE J563
Meets BC1.2 for DCP with one TPS2511 per port
Supports both USB 2.0 and 3.0 power switch requirements
TPS2511 USB power switch also offers the data line control to charge many devices
