LM3642: How to enable torch mode correctly

$

Part Number: LM3642

Hi team,

My customer is trying to enable torch mode by changing register(0x0A) to 0x02 (torch).

1. They tried to send (0x0A) to 0x02 (torch), but the LED is not lighted up, then they read back register 0x0B is 0x05.

2. They tried to send (0x0A) to 0x01 (indicator), then send (0x0A) to 0x02 (torch), the LED will be normal, and LED pin is 2.6V, OUT pin is 4.14V.

Does this mean hardware circuit/components are fine?

How do we set to torch mode correctly?

Please help to advise then we can check if there is something wrong.

Regards,

Allen
