LM43603DSUT datasheet by Texas Instruments

LM43603DSUT Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the LM43603DSUT can handle?
  The LM43603DSUT can handle a maximum input voltage of 42V, but it's recommended to keep it below 40V for reliable operation.
• How do I ensure the stability of the output voltage?
  To ensure stability, make sure to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Also, ensure that the output capacitor is placed close to the device.
• What is the minimum input capacitance required for the LM43603DSUT?
  The minimum input capacitance required is 10uF, but it's recommended to use a higher value (e.g., 22uF) for better performance and stability.
• Can I use the LM43603DSUT in a high-temperature environment?
  The LM43603DSUT is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage at higher temperatures to ensure reliable operation.
• How do I calculate the output voltage of the LM43603DSUT?
  The output voltage can be calculated using the formula: Vout = 0.8V x (1 + R1/R2), where R1 and R2 are the resistors in the feedback network.
