The TIDEP-0092 reference design provides a foundation for short-range radar (SRR) applications using the AWR1642 evaluation module (EVM). This design allows the estimation and tracking of the position (in the azimuthal plane) and velocity of objects in its field of view up to 80 m, travelling as fast as 90kmph. The AWR1642 is configured to be a multi-mode radar, meaning that, while it tracks objects at 80m, it can also generate a rich point cloud of objects at 20m, so that both cars at a distance, and smaller obstacles close-by can be detected.

This reference design outlines how to implement a three-stage, three-phase SiC-based AC/DC converter with bidirectional functionality. The high switching frequency of 50kHz reduces the size of the magnetic components in the filter design and therefore increases the power density. SiC MOSFETs with switching losses enable higher DC bus voltages up to 800V and lower switching losses, with peak efficiencies greater than 97%. This design can be configured as a two-stage or three-stage rectifier. For design information on DC/AC implementation, see TIDA-01606 . The system is controlled by a single C2000 microcontroller (MCU), TMS320F28379D, which generates PWM waveforms for all power electronic switching devices in all operating modes.
Interleaved Continuous Conduction Mode (CCM) Totem Pole (TTPL) Bridgeless Power Factor Correction (PFC) using high-bandgap GaN devices is an attractive power topology due to its high power efficiency and reduced size. This design illustrates the use of a C2000™ MCU and LMG3410 GaN FET module to control this power stage. To improve efficiency, this design uses adaptive dead time and phase shedding methods. Nonlinear voltage compensators are designed to reduce overshoot and undershoot during transients. This design chooses a software phase locked loop (SPLL) based approach to accurately drive the totem pole bridge. The hardware and software used in this design help reduce your time to market.

Li-Ion battery formation and electrical testing require accurate voltage and current control, usually to better than ±0.05% over the specified temperature range. This reference design proposes a solution for high-current (up to 50 A) battery tester applications supporting input (bus) voltages from 8 V–16 V and output load (battery) voltages from 0V–5V. The design utilizes an integrated multi-phase bidirectional controller, LM5170, combined with a high precisiondata converters and instrumentation amplifiers to achieve charge and discharge accuracies of 0.01% full scale. To maximize battery capacity and minimize battery formation time, the design uses highly-accurate constant current (CC) and constant voltage (CV) calibration loops with a simplified interface. All key design theories are described guiding users through the part selection process and optimization. Finally, schematic, board layout, hardware testing, and results are also presented.
This reference design demonstrates how our single-chip millimeter wave (mmWave) technology can be leveraged for reliable long-distance sensing in traffic monitoring and other applications. This reference design can use the IWR1642BOOST Evaluation Module (EVM) or the IWR1843BOOST Evaluation Module (EVM) and integrate the complete radar processing chain onto the IWR1642, IWR6843 or IWR8143 device. The processing chain includes analog radar configuration, analog-to-digital converter (ADC) capture, low-level FFT processing, and high-level clustering and tracking algorithms. This reference design is designed to be built on top of our mmWave SDK for a centralized software experience that includes APIs, libraries and tools for evaluation, development and data visualization.
Continuous-Conduction-Mode (CCM) Totem-pole power factor correction (PFC) is a simple but efficient power converter. To achieve 99% efficiency, there are many design details that need to be taken into account. The PMP20873 reference design uses TI’s 600VGaN power stage, LMG3410, and TI’s UCD3138 digital controller. The design overview provides more details on the CCM Totem-Pole topology operation, gives the detail design considerations of the circuit, and provides magnetics and firmware control design considerations. This converter design operates at 100KHz. A soft start at AC line crossover minimizes current spike and lowers THD. The PFC Firmware measures AC current and PFC output voltage in real-time and predicts the dead time needed for the switch node to complete a full swing. The adaptive dead time control effectively minimizes both switching loss and GaN FET body diode conduction loss. A GUI is available to support parameter setting and control loop tuning.

The insulation layer is laid first and then the copper. If the device on the front needs to be grounded, break the insulation layer and solder it to the copper.
