Hi, i would like to enquire with regards to the product number of TPS92638EVM evaluation module .

Part Number: TPS92638EVM
Other Parts Discussed in Thread: TPS92612-Q1


I would like to ask whether is this driver applicable to the LEDs that I want to connect with. Based on the manual, This driver has a total of 8 channel/strings. Each string can drives up to 70mA if connected in series and 560mA is connected in parallel. I have a total of 8 external LEDs that I wish to connect with. Each LED requires a current of 500mA to light up. Therefore my plan of doing it is to connect all the 8 channels/strings parallel and connect it with 8 LEDs. An illustration is shown as below. I would like to know whether is this method correct?

Next question that I have is that I have an additional 4 LEDs that need to be light up;2 blue LEDs and 2 white LEDs whereby each LED require 40mA to light up. This 4 LEDs will be connected on a new EMV. However, I wish to on the LED one colour at a time (meaning: 2 blue to be lighted up while 2 white is off; 2 White are lighted up while 2 bles are off). Is there any way for recommendation?
