TPS60400DBVRG4 datasheet by Texas Instruments

TPS60400DBVRG4 Frequently Asked Questions (FAQs)

• What is the recommended layout and placement for the TPS60400DBVRG4?
  The recommended layout and placement for the TPS60400DBVRG4 involves placing the input and output capacitors close to the device, using short and wide traces for the power lines, and keeping the analog and digital grounds separate. A 4-layer PCB with a solid ground plane is recommended.
• How do I ensure the stability of the TPS60400DBVRG4?
  To ensure stability, it is recommended to use a minimum output capacitance of 10uF, and to place a 10nF capacitor in parallel with the output capacitor to filter out high-frequency noise. Additionally, the input voltage should be well-regulated and the device should be operated within its recommended operating conditions.
• What is the maximum input voltage that the TPS60400DBVRG4 can handle?
  The maximum input voltage that the TPS60400DBVRG4 can handle is 5.5V. Exceeding this voltage may cause damage to the device.
• Can the TPS60400DBVRG4 be used in a high-temperature environment?
  The TPS60400DBVRG4 is rated for operation up to 85°C. However, the device's performance and reliability may degrade at higher temperatures. It is recommended to derate the device's output current and voltage at high temperatures.
• How do I calculate the output voltage of the TPS60400DBVRG4?
  The output voltage of the TPS60400DBVRG4 can be calculated using the formula: Vout = Vref x (1 + R1/R2), where Vref is the internal reference voltage (1.2V), and R1 and R2 are the resistors in the feedback network.
