Other Parts Discussed in Thread: TIDA-010247
Hi,
According to TIDA-010247 ref design REGIN input received voltage from B+ (the topmost battery) through transistor-based voltage converter circuit.
Why not to take voltage from between 2nd cell + (positive) point (e.g. VC2) and pass it to 5V LDO and then to REGIN? Wouldn't it be less power dissipation - from ~7V to 5V instead of ~24V (or more) to 5V ?
What am I missing here? Will it affect cell balancing in some way?
Thanks,
Leonid
