TPS82672SIPR datasheet by Texas Instruments

TPS82672SIPR Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance of the TPS82672SIPR?
  Texas Instruments provides a recommended PCB layout in the datasheet, but it's also recommended to follow general high-frequency PCB design guidelines, such as using a solid ground plane, minimizing trace lengths, and using a 4-layer stackup with a dedicated power plane.
• How do I ensure the TPS82672SIPR is stable and doesn't oscillate?
  To ensure stability, follow the recommended component values and PCB layout, and make sure to decouple the input and output with ceramic capacitors. Additionally, the datasheet provides a stability analysis section that can help you determine the stability of the converter.
• What is the maximum input voltage that the TPS82672SIPR can handle?
  The TPS82672SIPR has an absolute maximum input voltage rating of 6V, but the recommended operating input voltage range is 2.7V to 5.5V. Exceeding the absolute maximum rating can damage the device.
• Can I use the TPS82672SIPR in a high-temperature environment?
  The TPS82672SIPR has a junction temperature rating of 150°C, but the recommended operating temperature range is -40°C to 125°C. Exceeding the recommended operating temperature range can affect the device's performance and reliability.
• How do I calculate the output voltage of the TPS82672SIPR?
  The output voltage of the TPS82672SIPR can be calculated using the formula: VOUT = 0.8V x (1 + R1/R2), where R1 and R2 are the resistors used in the feedback network. The datasheet provides a detailed explanation of the output voltage calculation.
