MAX626CSA datasheet by Maxim Integrated Products

MAX626CSA Frequently Asked Questions (FAQs)

• What is the recommended input capacitor value for the MAX626CSA?
  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 voltage ripple and improve output voltage regulation.
• How do I ensure the MAX626CSA is stable and doesn't oscillate?
  To ensure stability, make sure to follow the recommended PCB layout guidelines, use a sufficient output capacitor value (at least 1uF), and keep the input and output capacitors close to the device. Also, avoid using long traces and minimize the loop area of the input and output connections.
• What is the maximum input voltage that the MAX626CSA can handle?
  The MAX626CSA can handle input voltages up to 12V, but it's recommended to operate within the specified input voltage range of 4.5V to 11V for optimal performance and reliability.
• Can I use the MAX626CSA in a high-temperature environment?
  The MAX626CSA is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage according to the temperature derating curve provided in the datasheet to ensure reliable operation.
• How do I calculate the output voltage of the MAX626CSA?
  The output voltage of the MAX626CSA is adjustable using an external resistor divider network. The output voltage can be calculated using the formula: VOUT = (R1 / R2) * (VREF - VFB), where R1 and R2 are the resistors in the divider network, VREF is the internal reference voltage (2.5V), and VFB is the feedback voltage (0.5V).
