The TPS78601DRBEVM is a comprehensive evaluation module (EVM) designed to provide developers with a platform for evaluating the TPS78601 low-power step-down DC-DC converter. It is a three-phase buck regulator, which means it can deliver regulated voltages from input voltages up to 30V. It is used to generate voltages as low as 0.25V, allowing a wide range of applications. The EVM includes a USB-connected GUI and allows engineers to graphically evaluate the performance of the TPS78601DRBEVM in real-time with an interactive graphical user interface (GUI).
Applications
The TPS78601DRBEVM is optimized to support multiple applications, including solar-powered energy harvesting/storage, ”always-on” system Supply, gateway, and processor-based systems. It is especially suitable for low-power system design including portable and handheld devices, Point-of-Sale systems, handheld scanners, blood glucose monitors, and miniature medical devices. Moreover, it can provide low-noise performance for noise-sensitive systems such as industrial applications (sensors, closed-loop controllers, etc.) and audio systems.
Connectivity
The TPS78601DRBEVM features a selectable 5V/3.3V I/O port to power instrumentation and test equipment. It is also equipped with a USB-C- type I/O port for user interface control and programming. This I/O port can also be used to provide control signals for real-time testing and measurements. Additionally, it has a UART serial port for communication with other components.
Design Features
The TPS78601DRBEVM offers a wide input voltage range from 4.5V to 30V and can provide output voltage regulation in the range of 0.25V to 12V with a maximum output current of 2.15A. Its switching frequency can be adjusted between 200kHz and 2MHz, allowing flexibility to optimize system performance. Importantly, it also provides short-circuit protection, as well as input undervoltage and over-voltage protection to ensure reliability. The step-down (buck) design also offers power savings over alternative topologies.
Working Principle
The TPS78601DRBEVM uses the three-phase interleaved buck converter topology to optimize efficiency at low output currents. It starts by rectifying the input voltage to generate a DC voltage which is reduced to a lower voltage by the switching regulator. It is enabled by a voltage pulse that is generated by an oscillator and then transferred to a low-side MOSFET and a high-side MOSFET in the buck converter circuit. This turns the MOSFETs on and off and lowers and raises the voltage. The lower voltage is transferred to the output through an inductor. The inductor at the output serves to smooth the ripple of the generated AC current from the input while providing stability.
Conclusion
The TPS78601DRBEVM is a comprehensive evaluation module designed to give engineers a platform to evaluate the TPS78601 low-power step-down DC-DC converter. It features a selectable 5V/3.3V I/O port, a USB-C type I/O port and a UART serial port. The step-down DC-DC converter provides output power regulation in the range of 0.25V to 12V and can support a maximum output current of 2.15A. Its three-phase interleaved buck converter topology helps optimize efficiency at low output currents, while providing safety features such as short-circuit protection and input over- or undervoltage protection.
