描述
The RTKA489000DE0000BU evaluation board is designed to demonstrate the performance of the RAA489000 buck-boost battery charger. From the PROG pin to GND, the resistor can be used to program the default value numbers of the battery in series, the switching frequency, and the adapter current limit charging function. The default value numbers can also be set by SMBus.
