Hi, TI expert
There is a request for a schematic review using the LM3405A from a customer.
The circuit diagram is attached as below.
Customer wanted to use 4 LED VF 1.5V in series, but because the BOOST PIN is 5.5V the maximum, I used another circuit in the application note. (5P) - see link below

The datasheet of the LED to be used is attached below.

Customer plan to use 2 or 4 IR LEDs.
We request you to review whether it is possible to apply the LED driver circuit.
(Are there any problems? Is there anything to be corrected?)
Please check. Thank you.
