TPS61040DBVRG4 datasheet by Texas Instruments

TPS61040DBVRG4 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS61040DBVRG4?
  The maximum input voltage that can be applied to the TPS61040DBVRG4 is 12V, but it's recommended to keep it below 10V for optimal performance and to prevent damage to the device.
• How do I ensure the stability of the output voltage?
  To ensure the stability of the output voltage, it's essential to use a suitable output capacitor with a low equivalent series resistance (ESR) and a sufficient capacitance value. A 10uF ceramic capacitor is recommended.
• What is the minimum input capacitance required for the TPS61040DBVRG4?
  The minimum input capacitance required for the TPS61040DBVRG4 is 1uF, but it's recommended to use a 4.7uF or 10uF capacitor to ensure stable operation.
• Can I use the TPS61040DBVRG4 in a high-temperature environment?
  The TPS61040DBVRG4 is rated for operation up to 85°C, but it's recommended to derate the output current and input voltage to ensure reliable operation in high-temperature environments.
• How do I calculate the output voltage of the TPS61040DBVRG4?
  The output voltage of the TPS61040DBVRG4 can be calculated using the formula: Vout = (R1 / R2) * (Vin - Vd), where R1 and R2 are the resistors in the feedback network, Vin is the input voltage, and Vd is the voltage drop across the internal diode.
