TPS77930DGK datasheet by Texas Instruments

TPS77930DGK Frequently Asked Questions (FAQs)

• What is the recommended input capacitor value for the TPS77930DGK?
  The recommended input capacitor value is 1uF to 10uF, with a voltage rating of at least 6.3V. A larger capacitor can be used to improve noise rejection and input ripple rejection.
• How do I ensure the TPS77930DGK is stable and does not oscillate?
  To ensure stability, make sure to follow the recommended layout guidelines, use a sufficient output capacitor (at least 2.2uF), and keep the input and output capacitors close to the device. Also, avoid using long traces and minimize the loop area of the power lines.
• What is the maximum output current I can draw from the TPS77930DGK?
  The maximum output current of the TPS77930DGK is 3A. However, the actual output current may be limited by the input voltage, output voltage, and thermal considerations. Be sure to check the device's thermal performance and power dissipation calculations to ensure reliable operation.
• Can I use the TPS77930DGK in a high-temperature environment?
  The TPS77930DGK is rated for operation up to 125°C. However, the device's performance and reliability may degrade at high temperatures. Be sure to check the device's thermal performance and power dissipation calculations to ensure reliable operation in your specific application.
• How do I adjust the output voltage of the TPS77930DGK?
  The output voltage of the TPS77930DGK can be adjusted by using a resistive divider network between the output and the ADJ pin. The output voltage can be calculated using the formula: Vout = 1.2V x (1 + R1/R2), where R1 and R2 are the resistors in the divider network.
