Other Parts Discussed in Thread: BQ25708, BQ40Z60, BQ25713, BQ25710
Hi, I would like to build a 1-4 cell USB programmable charger based on the BQ40Z80 and a Cypress based programmable PD chip. I have an early version utilizing the BQ40Z60 and requiring a 20V VBUS, but I would like it to be compatible with all possible USB voltages. Are there any recommended USB C aware buck-boost designs? I am thinking of utilizing the BQ25708/10/13 series, but I believe that would likely involve some redundant charge logic and FETs.
Thanks for any advice!
