We want to design a LiFePO4 Battery Charger Using TOP258YN.

Battery pack comprises 12.8V/20AH, Made up with 4series 6parallel Cell configuration of 3.2V/3.4AH each.

We already used a ready made charger which charge battery pack in CC/CV mode at 14.8V@5A Max.

We have some problem to understand different terms during software design phase:-

- What is CC Threshold Voltages When using CV/CC Operation mode?

- How can we differentiate between following Advanced output characteristics?
- Loose CV/CC Linear Transformer Replacement
- Loose CV/CC
- Tight CV Loose CC
- Tight CV/CC
