I come again for your help.
After some research, I decided to use tida-00623(5W) or tida-00762(1W).
tida762 is rated for 1W but its coil is rated for 3A?.
tida623 use a 6.3 uH coil.
So I compared schematics of tida762 and tida623 and found only some few differences and strange things.
- tida623 use 22 uF caps for pvin1 and 2 tida762 use 10 uF caps instead bq50002 documentation says it has to be 22 uF.
- tida623 shows pin 4 ilim with resistor tida762 has resistors and 3.3V bq500511 documentation says it's a reserved pin
- tida762 use some kind of filters before the coil
- tida623 use flim pin
Could you tell me if those differences are the reason of power abilities? and what I missed for the pin 4?
I think it's very close of what I want to do (2.5W and the previous coil).
thank you for your help
