Hi David,

Based on your reply for LM3404, I can use TPS92690 to drive 7pcs OSRAM SFH4726 LEDs(Vf=2.75V, If=1A max) when my input voltage is 12V, right? Is this the lowest cost option? Or do you have another recommendation for my requirement?

Thanks a lot!

Hello Mao,

I would look at the TPS92692 and TPS92691, the TPS92690 would also work. Are you planning on running this as a boost or a buck boost? Or other topology? The TPS92692 EVM is set up to run as a boost or boost to battery (buck boost).

Regards,

Hi Irwin,
My input voltage is 12V (no battery in my system). I would like to run it as boost, so do you think TPS92692 or TPS92691 is a better option than TPS92690?
Thanks.
Best regards,
Mao

Hello Mao,

Any of those will work. It depends on the features you wish to use. All of them have a boost EVM.
