TPS53314RGFR datasheet by Texas Instruments

TPS53314RGFR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS53314RGFR?
  The maximum input voltage that can be applied to the TPS53314RGFR is 6.5V, as specified in the datasheet. Exceeding this voltage may damage the device.
• How do I ensure the TPS53314RGFR is stable and does not oscillate?
  To ensure stability, follow the layout guidelines in the datasheet, use a low-ESR output capacitor, and add a 10nF ceramic capacitor between the VIN and GND pins to filter out noise.
• What is the minimum output capacitance required for the TPS53314RGFR?
  The minimum output capacitance required is 10uF, but it's recommended to use a 22uF or larger capacitor to ensure stability and optimal performance.
• Can I use the TPS53314RGFR in a high-temperature environment?
  The TPS53314RGFR is rated for operation up to 125°C, but the device's performance and reliability may degrade at high temperatures. Ensure proper thermal design and consider derating the output current at high temperatures.
• How do I calculate the output voltage of the TPS53314RGFR?
  The output voltage is set by the resistor divider network between the FB pin and GND. Use the formula: VOUT = 0.8V x (R1/R2 + 1), where R1 and R2 are the resistors in the divider network.
