Dear Sir,

Could we use 1.5uH inductor ?

What Resistance should be put on IADPT pin for 1.5uH inductor? table 3 on datasheet doesn't define it.

Hey Hugo,

Please be aware that charger's functionality and Electrical Characteristics table has only been fully characterized with 1uH, 2.2uH, and 3.3uH inductance values

However, to use 1.5uH, the RIADPT resistance should be approximately 110kOhm.
