TS321IDR datasheet by Texas Instruments

TS321IDR Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for the TS321IDR to minimize EMI?
  A good PCB layout for the TS321IDR involves keeping the input and output traces separate, using a solid ground plane, and placing the device close to the power source. Additionally, using a shielded inductor and keeping the switching node (SW) away from sensitive analog circuits can help minimize EMI.
• How do I choose the right inductor value for my application?
  The inductor value depends on the input voltage, output voltage, and switching frequency. A good starting point is to use the inductor value recommended in the datasheet. You can also use online inductor selection tools or consult with a TI engineer for more specific guidance.
• What is the maximum ambient temperature range for the TS321IDR?
  The TS321IDR is rated for operation from -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.
• Can I use the TS321IDR in a high-reliability or automotive application?
  Yes, the TS321IDR is qualified for automotive and high-reliability applications. It meets the AEC-Q100 standard for automotive applications and is also suitable for industrial and medical applications that require high reliability.
• How do I troubleshoot issues with the TS321IDR, such as oscillations or instability?
  To troubleshoot issues with the TS321IDR, start by checking the PCB layout, component values, and soldering quality. Use an oscilloscope to measure the input and output waveforms, and check for signs of oscillation or instability. Consult the datasheet and application notes for guidance on troubleshooting and debugging techniques.
