Other Parts Discussed in Thread: BQ25570
Hi there,
I took a look at the TIDA-00242 test report link: https://www.ti.com/lit/ug/tidu382/tidu382.pdf?ts=1655081493736.
On the First page, the power level is 1.8mW and the capacitance of the supercap is 47mF. Based on the graph on the right, the charging time to charge this 47mF supercap from 0Vto 4.2V took around 4041s. By using E=1/2*c*(V2^2-V1^2), the average output power calculated based on this graph is around 0.103mW. by using n=Poutput/Pinput, 0.1025mW/1.8mW*100%= 5.5%?
May I know if this calculation is correct? so that the bq25570 charger efficiency is only 5.5%? or have I made a mistake?
Massive Thanks.
