How Does The Smart Buck 3 Click Board™ Work?
The Smart Buck 3 Click Board™ is based on the TPS62366A, a processor supply with I2C compatible interface and a remote sense from Texas Instruments. Its dedicated inputs over the VIN terminal allow fast voltage transition while introducing input under voltage detection and lockout. In addition, it features over-temperature protection, a soft start, excellent DC output voltage regulation, and other robust operation/protection features. It offers a high-efficiency step-down conversion, with the highest efficiency towards low and highest output currents. This way, it increases the battery ON-time.
The TPS62366A uses the DCS-Control™ architecture and fully differential sensing to achieve precise static and dynamic transient output voltage regulation. This way, the output voltage security margins can be kept small. The used architecture supports PWM mode for medium and heavy load conditions and a Power Save mode for light loads. During the PWM mode, it works at the 2.5MHz frequency, and as the load decreases, the TPS62366A enters a Power Save mode (on this board set at 1.16V). This transition is seamless and does not affect output voltage transients.
In addition, the TPS62366A incorporates internal soft-start circuitry, which controls the output voltage ramp-up after enabling the device by eliminating the inrush current. The converter avoids excessive voltage drops of primary cells and rechargeable batteries with high internal impedance. During this procedure, the output voltage is monotonically ramped up to the threshold of the minimum programmable output voltage and further increases by the ramp rate settings to the programmed output voltage.
The Smart Buck 3 Click Board™ uses a standard 2-Wire I2C interface to communicate with the host MCU supporting Standard, Fast, and High-speed modes with a frequency of up to 3.4MHz. The I2C address is fixed and can not be changed.
This Click board™ can only be operated with a 3.3V logic voltage level. The board must perform appropriate logic voltage level conversion before using MCUs with different logic levels. However, the Click board™ comes equipped with a library containing functions and an example code that can be used, as a reference, for further development.
