MAX761CSA datasheet by Maxim Integrated Products

MAX761CSA Frequently Asked Questions (FAQs)

• What is the recommended input capacitor value for the MAX761CSA?
  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 MAX761CSA is stable and does not oscillate?
  To ensure stability, make sure to follow the recommended PCB layout guidelines, use a sufficient input capacitor, and add a 10nF to 100nF capacitor between the VOUT and GND pins to filter out high-frequency noise.
• What is the maximum input voltage that the MAX761CSA can handle?
  The MAX761CSA can handle a maximum input voltage of 18V, but it's recommended to operate within the 7V to 15V range for optimal performance and reliability.
• Can I use the MAX761CSA in a high-temperature environment?
  The MAX761CSA is rated for operation up to 125°C, but its performance and reliability may degrade at high temperatures. It's recommended to derate the output current and input voltage at high temperatures to ensure reliable operation.
• How do I calculate the output voltage of the MAX761CSA?
  The output voltage of the MAX761CSA is adjustable using the FB (feedback) pin. The output voltage can be calculated using the formula: VOUT = 1.25V x (R1 + R2) / R2, where R1 and R2 are the resistors connected to the FB pin.
