Other Parts Discussed in Thread: TPS54200,
Hello,
I am working on a medical imaging device which utilizes usage of illuminating the area of diagnosis of patients with IR laser diode technique and then capturing the illuminated surface using a monochrome camera for data capturing and image processing.
To power the said laser diode, I am planning to use constant current buck converter
Specs of the IR laser diode
So I was using TPS54200 as IR laser diode driver, but it seems it is not working out.

So I am planning to use TPS92200 as alternative.
So my question is, will TPS92200 be a good fit or is there some other IC which can do better job than TPS92200.
TPS92200 will be powered at 5V via USB. And I will also be using the dimming capability of IC, specifically I want to drive the IR laser diode in Analog dimming mode.
Thank you.
