Hi,
i want to know why does the charger read inductance value before the converter starts up?
i can't find more description about inductance detection in the datasheet.
9.3.5.1 Inductance Detection through IADPT Pin
The charger reads the inductance value through the resistance tied to IADPT pin before the converter starts up.
The resistances recommended for 1uH, 2.2uH and 3.3uH inductance are 93kΩ, 137kΩ and 169kΩ, respectively.
A surface mount chip resistor with ±3% or better tolerance must to be used for an accurate inductance detection.
Best regards,
Shubiao
