Hi
My customer designed the schematic with BQ24630, found the output voltage unstable and can't charge.
Attached the schematic for your reference.
When the adapter is powered on, the voltage at VBAT has been jumping, and the voltage at the VFB terminal I measured is also jumping.
The VBAT is connected to the battery, but can not charge.
The adapter uses DC24V, and set the battery voltage is about 18v.
According to the actual measurement, the PH output is 10v~18v.
Please give some suggestions.
Thanks
