Hi,
We have a 3s2p configuration of NCR18650b.
As given in the data sheet, the ripple current is taken 40% of maximum charge current Section 9.2.2.1.
For 40% of maximum charge current the calculated value of L is 4.6uH . In table 1 page 19, the suggested inductor value is given 3.3uH/2.2uH for 800kHz switching frequency.
When calculated the other way round i.e taking the inductor value as 3.3uH, the ripple current is 56% of maximum charge current.
Can you please suggest a value for the inductor in this case?
f=800kHz, input voltage =19.5V, duty cycle=0.5, max charge current .
Please find png file attached
Thank you
Regards
Harini krishna
