TPS73701DCQR datasheet by Texas Instruments

TPS73701DCQR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the TPS73701DCQR can handle?
  The TPS73701DCQR can handle input voltages up to 15V, but it's recommended to keep the input voltage below 13.2V for optimal performance and to prevent damage to the device.
• How do I ensure stability and prevent oscillations in the output voltage?
  To ensure stability and prevent oscillations, it's essential to follow the recommended layout and component selection guidelines provided in the datasheet, including the use of a 10uF ceramic capacitor at the output and a 1uF ceramic capacitor at the input.
• What is the minimum ESR (Equivalent Series Resistance) required for the output capacitor?
  The minimum ESR required for the output capacitor is 0.1 ohms. Using a capacitor with a lower ESR can cause instability and oscillations in the output voltage.
• Can I use a ceramic capacitor with a higher voltage rating than the output voltage?
  Yes, it's recommended to use a ceramic capacitor with a voltage rating higher than the output voltage to ensure reliability and prevent capacitor failure.
• How do I calculate the output voltage of the TPS73701DCQR?
  The output voltage of the TPS73701DCQR can be calculated using the formula: Vout = (R1 / R2) * (Vref), where R1 and R2 are the resistors connected to the FB pin, and Vref is the internal reference voltage (1.2V).
