LM25085: CCCV Realization

Part Number: LM25085
Other Parts Discussed in Thread: LM5175,

Dear, Sir.

My customer is applying LM5175 for Super Capacitor charging, so they are

utilizing CCCV function.

They are cos\dering the cost down system to change from LM5175 to others.

I found LM25085 looks having CCCV function because the target application

is Super Capacitor Charger & there is a Application Report, SNVA486A.

They are expecting following spec.

- Vin : 21 ~ 24v

- Voutmax : 18.5V

- Iout : 4.5A

I would like to make sure following at this time. Please give your advice.

1. I wonder LM25085 will be suitable to realize CCCV function?

2. I am not sure how to design using LM25085 for CCCV realization.

   Please let me know the design steps how to design for the realization.

Best Regards,

H. Sakai
