Texas Instruments provides a recommended layout and routing guide in their application note SLAA523, which includes guidelines for PCB layout, component placement, and routing to minimize noise and ensure optimal performance.
The DSD1793DBR can deliver high output currents, so it's essential to ensure that the PCB traces and components can handle the current. Use thick PCB traces, and consider adding current-sensing resistors to monitor the output current. Additionally, ensure that the output capacitors are rated for high ripple currents.
The DSD1793DBR's performance is affected by temperature, with the output voltage and current changing with temperature. The datasheet provides temperature coefficients for the output voltage and current, which can be used to estimate the performance over temperature. It's essential to consider temperature effects when designing the system.
To ensure stability, follow the recommended layout and routing guidelines, and use the recommended output capacitors and resistors. Additionally, ensure that the input voltage is within the recommended range, and that the output is properly decoupled. If oscillations occur, try adding a small capacitor (e.g., 10nF) between the output and ground.
The DSD1793DBR is a commercial-grade device, but it can be used in high-reliability or automotive applications with proper design and testing. Ensure that the device is operated within its recommended specifications, and that the system is designed to meet the required reliability and safety standards.
