Hello expert,
May we know if you can provide RSET setting range? I would like to know the maximum/minimum value for RSET and want to check if 72mA is okay to set in TPS61169. Thanks a lot!!
Best regards,
Ann Lien

hi Ann
Normally we firstly check the available LED current and then set RSET based on the current. You can refer to the formula in 9.2.2.1. According to the input voltage, output voltage and inductance, the ripple current can be obtained. Limit by 1.2A internal Fet, the max LED current can be derived.
