Hi team,
What is the maximum duty cycle of bq24770 for 4-cell battery (4.2V/cell) application?
How much minimum input voltage is required for proper operation? Thanks!
Best regards,
Sam Ting

Hey Sam,
For the converter to operate properly, the VCC voltage must be higher than the VBAT voltage by the EC table parameter V(VCC-BAT_RISE).
You can also refer to section 8.3.2 Adapter Detect and ACOK Output in the datasheet as the ACOK requirements match the input voltage requirements related to VCC.
