CMI 102: ACT5102QI102
CMI 102 has default settings that are appropriate for most typical applications. It operates with a 500kHz switching
frequency to provide an optimal tradeoff between overall size and efficiency. The table below shows the default register
settings. The difference between the ACT5101QI102 and ACT5102QI102 is that the ACT5102QI102 has external volt-
age feedback and does not have the ADC functionality.
