LM26420XMHX/NOPB Frequently Asked Questions (FAQs)

  • A good PCB layout for the LM26420XMHX/NOPB involves keeping the input and output capacitors close to the IC, using a solid ground plane, and minimizing the length of the input and output traces. A 4-layer PCB with a dedicated power plane and a solid ground plane is recommended.
  • To ensure stability, it's essential to follow the recommended component values and PCB layout guidelines. Additionally, ensure that the output capacitor is of high quality and has a low equivalent series resistance (ESR). A minimum output capacitance of 10uF is recommended.
  • The maximum input voltage that can be applied to the LM26420XMHX/NOPB is 42V. Exceeding this voltage can cause damage to the device.
  • The output voltage of the LM26420XMHX/NOPB can be calculated using the formula: Vout = (R1/R2) * (1.22V). R1 and R2 are the resistors connected to the FB pin.
  • The maximum output current that the LM26420XMHX/NOPB can deliver is 2A. However, the actual output current may be limited by the input voltage, output voltage, and thermal considerations.
