11 Power Supply Recommendations

The BQ25968 can be powered by a standard power supply capable of meeting the input voltage and current requirements for evaluation. In the actual application, it must be used with a wall adapter that supports USB Power Delivery (PD) Programmable Power Supply (PPS) specifications.
