Hi
Now our customer doing design BQ25703A Charger system.
Customer want to measure Gain Phase by self.
This device has COMP1 and COMP2 pin and connected to several Resistance and capacitor.
We understood this device is Buck Boost type and need 2 type Phase compensation as each one,
Customer want to strong request us , Could you tell us how to measure Phase gain characteristics at this BQ25703A ??
Because of They are Japan company and they has Company internal rule " measure for Gain Phase by self ".
Could you answer this question??
1) About COMP1 and COMP2
If we do measure Gain Phase , we need External Resister add to COMP1 and COMP2 as injection signal.
Where we need add this injection Signal with Resister ?? Could you tell us this Resister Add Point ??
2) About Gain Phase characteristics
Do you have some document , How to measure Gain Phase characteristics ??
If have this document , Could you send us ??
Thanks and Regard
