LM3526MX-L/NOPB datasheet by Texas Instruments

LM3526MX-L/NOPB Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LM3526MX-L/NOPB?
  The maximum input voltage that can be applied to the LM3526MX-L/NOPB is 40V, but it's recommended to keep it below 30V for reliable operation.
• How do I ensure the LM3526MX-L/NOPB operates within its safe operating area (SOA)?
  To ensure the LM3526MX-L/NOPB operates within its SOA, make sure to keep the input voltage, output current, and junction temperature within the recommended limits specified in the datasheet.
• What is the purpose of the bootstrap capacitor (CBOOT) in the LM3526MX-L/NOPB?
  The bootstrap capacitor (CBOOT) is used to generate the high-side gate drive voltage for the internal power MOSFET. It's essential for proper operation of the device.
• Can I use the LM3526MX-L/NOPB in a synchronous buck converter configuration?
  Yes, the LM3526MX-L/NOPB can be used in a synchronous buck converter configuration, but it requires an external low-side MOSFET and a Schottky diode for efficient operation.
• How do I calculate the output voltage ripple of the LM3526MX-L/NOPB?
  The output voltage ripple of the LM3526MX-L/NOPB can be calculated using the formula: ΔVout = (Iout * ESL) / (Cout * fsw), where ESL is the equivalent series inductance of the output capacitor, Cout is the output capacitance, and fsw is the switching frequency.
