LM4990MMX/NOPB Frequently Asked Questions (FAQs)

  • A good PCB layout for the LM4990MMX/NOPB involves keeping the input and output capacitors close to the device, using a solid ground plane, and minimizing trace lengths and widths to reduce parasitic inductance and capacitance.
  • To ensure stability, make sure to follow the recommended component values and PCB layout, and add a 10nF capacitor between the COMP and FB pins to improve phase margin. Also, avoid using long traces and minimize the distance between the device and the output capacitor.
  • The LM4990MMX/NOPB can handle input voltages up to 15V, but it's recommended to keep the input voltage below 12V to ensure reliable operation and minimize power dissipation.
  • The LM4990MMX/NOPB is rated for operation up to 125°C, but its performance may degrade at high temperatures. It's recommended to derate the device's output current and voltage at high temperatures to ensure reliable operation.
  • The output voltage of the LM4990MMX/NOPB can be calculated using the formula: Vout = 1.23V x (1 + R1/R2), where R1 and R2 are the resistors connected between the OUT and FB pins.
