MAX1793EUE25+ datasheet by Maxim Integrated Products

MAX1793EUE25+ Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for the MAX1793EUE25+ to ensure optimal performance?
  A good PCB layout for the MAX1793EUE25+ involves keeping the input and output capacitors close to the IC, using a solid ground plane, and minimizing the length of the traces connecting the IC to the capacitors and resistors. A 4-layer PCB with a dedicated power plane and a solid ground plane is recommended.
• How do I ensure the stability of the output voltage in the MAX1793EUE25+?
  To ensure the stability of the output voltage, it is essential to choose the correct output capacitor value and type. A minimum capacitance of 10uF with an ESR of 1ohm or less is recommended. Additionally, the output capacitor should be placed close to the IC, and the feedback resistors should be chosen to ensure a stable output voltage.
• What is the maximum input voltage that the MAX1793EUE25+ can handle?
  The MAX1793EUE25+ can handle a maximum input voltage of 5.5V. Exceeding this voltage may damage the IC.
• How do I calculate the output voltage of the MAX1793EUE25+?
  The output voltage of the MAX1793EUE25+ can be calculated using the formula: Vout = (R1/R2) * (Vref), where R1 and R2 are the feedback resistors, and Vref is the internal reference voltage (1.25V).
• What is the quiescent current of the MAX1793EUE25+?
  The quiescent current of the MAX1793EUE25+ is typically around 50uA. This current is drawn from the input voltage source when the IC is in operation.
