TPS62821DLCR Frequently Asked Questions (FAQs)

  • A good PCB layout for the TPS62821DLCR involves placing the input and output capacitors close to the device, using a solid ground plane, and minimizing the loop area of the power traces to reduce EMI. TI provides a recommended PCB layout in the datasheet and application notes.
  • Choose input capacitors with a low ESR and a voltage rating that exceeds the maximum input voltage. For output capacitors, choose ones with a low ESR and a voltage rating that exceeds the output voltage. The datasheet provides guidelines for capacitor selection.
  • The TPS62821DLCR has an operating junction temperature range of -40°C to 125°C. However, the maximum ambient temperature range depends on the specific application and thermal design. TI provides thermal design guidelines in the datasheet and application notes.
  • To ensure stability, follow the recommended PCB layout, choose the right input and output capacitors, and ensure the output voltage is within the specified range. Additionally, add a small ceramic capacitor (e.g., 10nF) between the VOUT and GND pins to improve stability.
  • The TPS62821DLCR has a maximum output current of 2A. For high-current applications, consider using multiple devices in parallel or using a different device with a higher current rating. TI provides guidance on paralleling devices in the datasheet and application notes.
