TPS62619YFDR datasheet by Texas Instruments

TPS62619YFDR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS62619YFDR?
  The maximum input voltage that can be applied to the TPS62619YFDR is 5.5V, as specified in the absolute maximum ratings section of the datasheet. Exceeding this voltage may damage the device.
• How do I ensure the TPS62619YFDR is stable and does not oscillate?
  To ensure stability, follow the layout guidelines in the datasheet, use a high-quality output capacitor with low ESR, and keep the input and output capacitors close to the device. Additionally, ensure that the input voltage is within the recommended range and the output current is within the specified limits.
• What is the minimum input capacitance required for the TPS62619YFDR?
  The minimum input capacitance required for the TPS62619YFDR is 10uF, as specified in the datasheet. However, it is recommended to use a higher value capacitor (e.g., 22uF) to ensure stability and improve transient response.
• Can I use the TPS62619YFDR in a high-temperature environment?
  The TPS62619YFDR is rated for operation up to 125°C, but its performance may degrade at high temperatures. Ensure that the device is operated within the recommended temperature range and that the thermal design is adequate to prevent overheating.
• How do I calculate the output voltage of the TPS62619YFDR?
  The output voltage of the TPS62619YFDR can be calculated using the formula: VOUT = 0.6V x (1 + R1/R2), where R1 and R2 are the resistors connected to the FB pin. The output voltage range is from 0.6V to 3.3V.
