TPS92611-Q1: TPS92611-Q1 white LED vs RGB LED

Part Number: TPS92611-Q1

Hi 

I wonder is there any specific differnt point when using TPS92611-Q1 for white LED or RGB LED.

For analyze this content, I try to simulate this part on Pspice.

But I cannot find RGB Led (or red led).

Is there RGB led model on Pspice?

And for using TPS92611, those the type of LED matter?

    Hi Dustin,

    For the functions on Pspice, you may need to inquire the software support team. For white and red LED, you can refer to their datasheet for the difference between them. Normally, the forward voltage (Vf) of red LED is lower than white LED in auto lighting. The threshold for various diagnosis is well designed for any color LED. So the type should not matter here. But if you need to do a simulation, you may need to choose the Vf <=2.5V for red LED.

    BR, Gracie
