Other Parts Discussed in Thread: TPS92691

Hi sir,

May I know TI's Boost LED Driver such as TPS92691/0 why is always none-sync topology?

Could you help provide can replace Lineartech's LT3756 device?

The TPS92691 would be the closest device TI has to that part. I am not sure what you mean by none-sync however? In either case the SYNC function on the TPS92691 is optional. You can just set a constant switching frequency with a resistor to ground just like the LT device.

Hi sir,
My sync topology mean is sync FET replace general Diode for boost converter.

I see. No, we do not have any synchronous boost LED drivers. You may be able to configure a voltage mode synchronous boost controller to run constant current, but I am not familiar with those devices.
