Hello,
I’m looking to charge and balance a 2S solution, with a wide input voltage range, without the need for an additional buck / boost converter. Bucking down to 5v for the MP2672A, only to have it boost again to the pack voltage (~ 8.4 - 8.7v depending on the chemistry) isn’t ideal and will generate a lot of heat in our consumer product.
- Wide input range from 5v - 12v
- I2C Control desirable, plus standalone defaults
- 2S, Balanced
- 4.2 x 2 or 4.35 x 2 charged voltages (8.4v / 8.7v pack)
- No need to buck then boost
How would these two chips even be connected, or is there a better solution I’m not thinking of?
