Posted on November 09, 2015 at 19:09I am designing a breakout (stamp) board for this controller and I am a bit confused about the hardware configuration of the USB OTG section. Can the VUSB be 5 V, the standard voltage from any USB source? If I want to have my device serve as either host of client, can I connect the VUSB to USB VIN (5V) and power the 3V3 VDD of the board using the same USB VIN regulated to 3V3 with an LDO regulator. I would call this a standard configuration, but the data sheet says VUSB is 3 - 3.6 V. So how can I connect a USB voltage source that is typically 5 V?
