Hello,

I am looking for a CV/CC DC-DC PCM to re-charge a Lifepo4 battery pak from a car ignition source. At times, I might need to boost input voltage to output voltage by a small amount (for example 13v to 14.2v).  I was looking at Drok model 200179 which claims to be a boost (step-up) converter.  However, I also like the model 200220 which has a bit more power output and a few extra features. The 200220 lists as a step-down converter, but the design seems similar to the 200179.  Some similar step-down models seem to claim output voltage would be approx 0.8v lower than input voltage.

Can you confirm if model 200179 can boost 13v to 14.2v if CV is adjusted properly? (and when not in current limit mode).

Can you confirm if model 200220 could boost voltage in similar way, or if not, how close to input voltage could it get?

Or are there any other suggested models. I prefer to have CC charging of at least 3A, but would like possibility of say 6A.
