LM3524DM Frequently Asked Questions (FAQs)

  • The LM3524DM can handle input voltages up to 40V, but it's recommended to keep it below 35V for reliable operation.
  • 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.
  • The minimum ESR required for the output capacitor is 0.1 ohms. Using a capacitor with a lower ESR may cause instability or oscillation.
  • 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.
  • 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.
