LM2524DN/NOPB datasheet by Texas Instruments

LM2524DN/NOPB Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the LM2524DN/NOPB can handle?
  The LM2524DN/NOPB can handle input voltages up to 42V, but it's recommended to keep the input voltage below 40V for reliable operation.
• How do I ensure the stability of the output voltage?
  To ensure stability, it's essential to use a minimum output capacitance of 10uF, and the output capacitor should be placed as close to the output pin as possible. Additionally, the input capacitor should be at least 1uF.
• What is the maximum output current that the LM2524DN/NOPB can provide?
  The LM2524DN/NOPB can provide up to 3A of output current, but it's recommended to keep the output current below 2.5A for reliable operation.
• How do I choose the right inductor value for my application?
  The inductor value depends on the input voltage, output voltage, and switching frequency. A good starting point is to use the inductor value recommended in the datasheet (e.g., 10uH for the LM2524DN/NOPB). You can then adjust the value based on your specific application requirements.
• What is the purpose of the enable pin (EN) on the LM2524DN/NOPB?
  The enable pin (EN) is used to turn the regulator on or off. When the EN pin is high, the regulator is enabled, and when it's low, the regulator is disabled. This pin can be used to implement power sequencing or to turn off the regulator when not in use.
