BQ25720, an NVDC battery buck-boost charge controller, chargers 1S-4S batteries from a wide-range input sources (3.5V-26V).
There are multiple loops inside the charger, for example, input voltage, input current, system voltage, charge current, charge voltage etc. To simplify the design process, TI provides two sets of compensation network. These compensation values have been verified by design, and validated during the product development process, at different input and with different battery cell configuration. There is no benefit to further optimize the compensation networks.
Therefore, it is NOT recommended to change the compensation values in the buck-boost charger.
