: The center of the QFN-16 package features an exposed thermal ground pad. Ensure this pad is cleanly reflowed to the PCB to allow adequate heat dissipation.
The laptop runs smoothly on an AC adapter but cannot push current into the battery pack, often caused by a blown high-side current sensor circuit or a damaged SMBus line.
The datasheet’s PSRR (Power Supply Rejection Ratio) is poor by design (GaAs FETs are not op-amps). If you have a 100 mVpp ripple on your 3.3V rail, you will see that ripple as phase noise on your output. 8681l ic datasheet
