LM25116MHX/NOPB datasheet by Texas Instruments

LM25116MHX/NOPB Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LM25116MHX/NOPB?
  The maximum input voltage that can be applied to the LM25116MHX/NOPB is 42V, but it's recommended to keep it below 40V for reliable operation.
• How do I ensure the stability of the output voltage in the LM25116MHX/NOPB?
  To ensure the stability of the output voltage, it's essential to use the recommended output capacitor value and type, and to keep the output capacitor close to the device. Additionally, the input capacitor should be placed close to the input pin.
• What is the maximum output current that the LM25116MHX/NOPB can deliver?
  The maximum output current that the LM25116MHX/NOPB can deliver is 1.5A, but it's recommended to keep it below 1.2A for reliable operation and to prevent overheating.
• How do I calculate the output voltage of the LM25116MHX/NOPB?
  The output voltage of the LM25116MHX/NOPB can be calculated using the formula: Vout = 0.8V x (1 + R1/R2), where R1 and R2 are the resistors connected to the FB pin.
• What is the purpose of the EN pin in the LM25116MHX/NOPB?
  The EN (Enable) pin is used to enable or disable the device. When the EN pin is pulled high, the device is enabled, and when it's pulled low, the device is disabled.
