Texas Instruments provides a recommended PCB layout and thermal management guide in their application notes (SLVAE03) and layout files (CAHCT1G86QDCKR1.tzr). It's essential to follow these guidelines to ensure optimal performance, especially for high-frequency and high-power applications.
The selection of input and output capacitors depends on the specific application, frequency range, and desired performance. TI recommends using X7R or X5R ceramic capacitors with a voltage rating of at least 2x the maximum input voltage. For more information, refer to the TI Capacitor Selection Guide (SLUA717) and the device's datasheet.
The CAHCT1G86QDCKR1 has an operating temperature range of -40°C to 125°C. However, the device's performance and reliability may degrade at extreme temperatures. It's essential to ensure proper thermal management and consider derating the device's performance at high temperatures.
To ensure EMC and reduce EMI, follow TI's guidelines for PCB layout, grounding, and shielding. Use a multi-layer PCB with a solid ground plane, and consider adding EMI filters or shielding components to your design. Additionally, ensure that your design meets the relevant EMC standards and regulations.
TI recommends using a reflow soldering process with a peak temperature of 260°C (max) and a soldering time of 30 seconds (max). Ensure that the device is handled and stored in accordance with the JEDEC standards for moisture sensitivity (MSL 3). For more information, refer to the TI Soldering and Assembly Guide (SLUA717).
