LM3524DM datasheet by Texas Instruments

LM3524DM Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the LM3524DM can handle?
  The LM3524DM can handle input voltages up to 40V, but it's recommended to keep it below 35V for reliable operation.
• How do I ensure the LM3524DM is stable and doesn't oscillate?
  To ensure stability, make sure to follow the recommended layout and component placement guidelines, use a sufficient output capacitor, and add a compensation capacitor (Ccomp) between pins 1 and 16.
• What is the minimum ESR (Equivalent Series Resistance) required for the output capacitor?
  The minimum ESR required for the output capacitor is 0.1 ohms. Using a capacitor with a lower ESR may cause instability or oscillation.
• Can I use the LM3524DM in a high-temperature environment?
  The LM3524DM is rated for operation up to 125°C, but its performance may degrade at high temperatures. Make sure to derate the output current and voltage according to the temperature derating curves in the datasheet.
• How do I calculate the output voltage ripple of the LM3524DM?
  The output voltage ripple can be calculated using the formula: ΔVout = (Iout * ESR) / (fsw * Cout), where Iout is the output current, ESR is the output capacitor's equivalent series resistance, fsw is the switching frequency, and Cout is the output capacitance.
