TPS54821RHLR Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the TPS54821RHLR is 6.5V, as specified in the datasheet. Exceeding this voltage may damage the device.
  • To ensure stability, follow the layout guidelines in the datasheet, use a low-ESR output capacitor, and add a 10nF-100nF ceramic capacitor between the VIN and GND pins to filter out noise.
  • The minimum input capacitance required is 4.7uF, as specified in the datasheet. Using a smaller capacitor may cause instability or oscillations.
  • The TPS54821RHLR is rated for operation up to 125°C. However, the device's performance and reliability may degrade at high temperatures. Ensure proper thermal design and consider derating the device's specifications accordingly.
  • The output voltage of the TPS54821RHLR is set by the resistive divider network connected to the FB pin. Use the formula: VOUT = 0.8V x (R1 + R2) / R2, where R1 and R2 are the resistors in the divider network.
