LM3405A: Schematic Review Request (LM3405A)

Part Number: LM3405A

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.
