TPS60500DGSRG4 datasheet by Texas Instruments

TPS60500DGSRG4 Frequently Asked Questions (FAQs)

• What is the recommended layout and placement for the TPS60500DGSRG4 to minimize noise and ensure optimal performance?
  TI recommends a compact layout with the input and output capacitors placed close to the device, and the feedback resistors placed close to the FB pin. A solid ground plane and a separate power plane for the input and output are also recommended to minimize noise and ensure optimal performance.
• How do I choose the right input and output capacitors for the TPS60500DGSRG4?
  Choose input capacitors with low ESR (Equivalent Series Resistance) and high ripple current rating to minimize voltage drops and ensure stable operation. For output capacitors, select ones with low ESR and high capacitance to filter out noise and ensure stable output voltage. TI recommends using ceramic or tantalum capacitors with X5R or X7R dielectrics.
• What is the maximum input voltage that the TPS60500DGSRG4 can handle?
  The TPS60500DGSRG4 can handle input voltages up to 18V, but it's recommended to keep the input voltage below 15V to ensure optimal performance and reliability.
• How do I adjust the output voltage of the TPS60500DGSRG4?
  The output voltage of the TPS60500DGSRG4 can be adjusted by changing the ratio of the feedback resistors (R1 and R2) connected to the FB pin. Use the formula Vout = Vref * (1 + R2/R1) to calculate the desired output voltage, where Vref is the internal reference voltage (1.2V).
• What is the typical startup time for the TPS60500DGSRG4?
  The typical startup time for the TPS60500DGSRG4 is around 1ms, but this can vary depending on the input voltage, output voltage, and load conditions.
