LM25037QMTX/NOPB datasheet by Texas Instruments

LM25037QMTX/NOPB Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  A good PCB layout for the LM25037QMTX/NOPB should include a solid ground plane, a separate power plane for the input voltage, and a heat sink attached to the exposed pad of the IC. The layout should also minimize the distance between the input capacitors and the IC.
• How do I ensure the stability of the output voltage?
  To ensure the stability of the output voltage, it is recommended to use a minimum output capacitance of 10uF, and to place the output capacitor close to the output pin of the IC. Additionally, the output voltage can be stabilized by adding a small ceramic capacitor (e.g. 10nF) in parallel with the output capacitor.
• What is the maximum input voltage that can be applied to the IC?
  The maximum input voltage that can be applied to the LM25037QMTX/NOPB is 42V. Exceeding this voltage may cause damage to the IC.
• How do I calculate the output voltage of the IC?
  The output voltage of the LM25037QMTX/NOPB can be calculated using the following formula: Vout = 0.8V x (1 + R1/R2), where R1 and R2 are the resistors used in the feedback network.
• What is the maximum output current that the IC can deliver?
  The maximum output current that the LM25037QMTX/NOPB can deliver is 3A. Exceeding this current may cause the IC to overheat or fail.
