MAX749CSA+ Frequently Asked Questions (FAQs)

• What is the recommended layout and placement for the MAX749CSA+?
  The recommended layout and placement for the MAX749CSA+ involves keeping the input and output capacitors close to the IC, using a solid ground plane, and minimizing the length of the traces to reduce noise and EMI.
• How do I ensure the MAX749CSA+ is stable and doesn't oscillate?
  To ensure stability, make sure to follow the recommended component values and layout guidelines, and add a 10nF capacitor between the COMP and GND pins to prevent oscillation.
• What is the maximum input voltage that the MAX749CSA+ can handle?
  The MAX749CSA+ can handle input voltages up to 18V, but it's recommended to keep the input voltage below 15V for optimal performance and reliability.
• How do I adjust the output voltage of the MAX749CSA+?
  The output voltage of the MAX749CSA+ can be adjusted by changing the ratio of the resistors R1 and R2 connected to the FB pin, according to the formula: Vout = 1.25V x (1 + R2/R1).
• What is the maximum output current that the MAX749CSA+ can deliver?
  The MAX749CSA+ can deliver up to 3A of output current, but it's recommended to keep the output current below 2A for optimal performance and reliability.
