- $\eta$ = estimated converter efficiency
(This is taken from section 8.2.2.2 of the datasheet)
First, to calculate the duty cycle boost we can plug in the output voltage (3.3V) and the "minimum input voltage in boost mode" which for the BQ25985 is listed as 2.304V
$$D = \frac{{3.3 - 2.304}}{3.3} = 0.302$$
First, to calculate the duty cycle boost we can plug in the output voltage (3.6V) and the "minimum input voltage in boost mode" which for the BQ25985 is listed as 2.304V
$$D = \frac{{3.6 - 2.304}}{3.6} = 0.302$$
Now calculating for $I_{PEAK}$ using the values
- $D = 0.302$ (calculated previously)
- $f = 2.5$ (MHz, typical stated in datasheet)
