MAX873BCSA datasheet by Maxim Integrated Products

MAX873BCSA Frequently Asked Questions (FAQs)

• What is the recommended input capacitor value for the MAX873BCSA?
  The recommended input capacitor value is 1uF to 10uF, depending on the input voltage and output current requirements. A larger capacitor value can help to reduce input ripple and improve output stability.
• How do I ensure the MAX873BCSA is stable and does not oscillate?
  To ensure stability, make sure to follow the recommended PCB layout guidelines, use a sufficient input capacitor, and keep the output capacitor value within the recommended range. Also, avoid using a capacitor with a high equivalent series resistance (ESR) on the output.
• What is the maximum output current capability of the MAX873BCSA?
  The maximum output current capability of the MAX873BCSA is 3A. However, the actual output current capability may be limited by the input voltage, output voltage, and thermal considerations.
• Can I use the MAX873BCSA in a high-temperature environment?
  The MAX873BCSA is rated for operation up to 125°C. However, the device's performance and reliability may be affected at high temperatures. It's recommended to derate the output current and ensure proper thermal management to prevent overheating.
• How do I calculate the output voltage of the MAX873BCSA?
  The output voltage of the MAX873BCSA can be calculated using the formula: VOUT = VREF x (1 + R1/R2), where VREF is the internal reference voltage (1.25V), R1 is the feedback resistor, and R2 is the divider resistor.
