Hello everyone,
I am designing the power system of a new circuit. It will receive an analog video signal and then be able to split that video signal to multiple outputs. I would like to have multiple ways to power the circuit depending on the application. One way to power the device will be by apply a DC voltage to the circuit and the other way will be by using the 5V from the USB.
The USB needs to be connected at all times for the communication. We may use this circuit in other places as just a receiver/splitter and the USB will not be required and it will be powered from the DC voltage. We may have an application where we don't want the DC voltage and will power just from USB. For the current application we will have the USB and adapter connected at the same time.
I am having problems trying to find a chip where I can have an adapter plugged in and a USB at the same time. If someone could please point me in the right direction of how to accomplish this it would be greatly appreciated. I am fairly new to electronics design (only graduated a year ago).
Thanks!
