TPS75225QPWPRG4 datasheet by Texas Instruments

TPS75225QPWPRG4 Frequently Asked Questions (FAQs)

• What is the recommended input capacitor value for the TPS75225QPWPRG4?
  The recommended input capacitor value is 1uF to 10uF, with a voltage rating of at least 6.3V. A larger capacitor can be used for improved noise rejection and transient response.
• How do I ensure the TPS75225QPWPRG4 is stable and doesn't oscillate?
  To ensure stability, follow the layout guidelines in the datasheet, keep the input and output capacitors close to the device, and use a low-ESR capacitor for the output. Additionally, avoid using a capacitor with a high ESL (Equivalent Series Inductance) on the output.
• What is the maximum output current I can draw from the TPS75225QPWPRG4?
  The maximum output current is 2.5A, but it's recommended to derate the output current based on the ambient temperature and the device's thermal characteristics to ensure reliable operation.
• Can I use the TPS75225QPWPRG4 in a high-temperature environment?
  The TPS75225QPWPRG4 is rated for operation up to 125°C, but the device's performance and reliability may degrade at high temperatures. It's essential to consider the device's thermal characteristics and derate the output current accordingly.
• How do I calculate the output voltage of the TPS75225QPWPRG4?
  The output voltage is set by the resistor divider network (R1 and R2) connected to the FB pin. The output voltage can be calculated using the formula: Vout = 1.25V x (1 + R2/R1).
