Hello,
Is it possible to pull down on the COMP pin like this diagram to implement constant current control?
Thank you, Keith

Hi,
We are looking into your request and give you feedback on Monday.
Hi Zhao,
Sorry for the drawing. That is not a zener, it is a diode to only pull down on COMP pin.
What we want to do is set Vout = 21.0V, and then do constant current control for charging a 5s battery.
The max charging current will be 6A.
Thanks very much for your help. Keith
Hi, Keith
TPS65286 uses peak current mode, the COMP voltage repsesnts peak inductor current, why do you want to pull down COMP voltage?
BTW, suggest using charger IC to charge battery.
