Part Number: BQ25703A

Hi sir,

Thank you for the response,The RC network design is not mentioned anywhere for the buck-boost compensation pin of BQ25703A IC ,can I get any details related to that....

THANK YOU.

The BQ25703A EVM provides an example RC compensation network which works for a wide input range and different cell configurations. It has been verified previously. Suggest following the standard EVM as a starting point. Moreover, the compensation can be further optimized by experiments.

Thank you for the response Sir,

Sir I just want to know how the RC network is designed with those specified designs,And one more thing for the same IC BQ25703A how do i only use it as to charge the battery not to have a system...

The RC network can be designed by simulation, or by experiments by optimizing the charge current step responses.

You are totally fine to use it without a system load.

Thank you for the response Sir,

Is their any change required to be made in the circuit without system load,And one more thing Sir my adapter rating is 15v,2.4A and my battery needs to charged at 11.1V/3.1A will it work fine and I am using esp32 as controller for this...
