HOW DOES IT WORK?
Buck-Boost 4 Click is based on the TPS55289, a buck-boost converter from Texas Instruments. It can smoothly transition between buck mode, buck-boost mode, and boost mode according to the input voltage and the set output voltage. It operates in buck mode when the input voltage exceeds the output voltage and in boost mode when the input voltage is less than the input voltage. When the input voltage is close to the output voltage, it alternates between one-cycle buck mode and one-cycle boost mode. Depending on the load currents, the converter can work in PWM or PFM mode. The switching frequency is set with a resistor to a little less than 1MHz.

Buck-Boost 4 Click uses a standard 2-wire I2C interface to communicate with the host MCU supporting clock frequency of up to 1MHz. The I2C address can be selected over the ADDR SEL jumper. You can turn off the device by setting the EN pin to a LOW logic state. The fault indication is available over the INT pin.
This Click board™ can operate with either 3.3V or 5V logic voltage levels selected via the VCC SEL jumper. This way, both 3.3V and 5V capable MCUs can use the communication lines properly. Also, this Click board™ comes equipped with a library containing easy-to-use functions and an example code that can be used as a reference for further development.
