Evaluation board implementation
2.1
Charging circuitry
The evaluation board implements a solution with an external low-voltage DC supply.
To obtain a constant voltage or constant current during various stages, the ST7
microcontroller measures the battery voltage (VBAT) and current (IBAT). Along with this
feedback, it provides the regulated output power to the battery under charge using a non-
inverting buck-boost converter circuit.
The buck boost converter is controlled by 2 PWM signals coming from the microcontroller as
shown in basic circuit diagram (Figure 4). For more details on the buck/boost converter,
please refer to AN2389.
