MAX5160LEUA+ datasheet by Maxim Integrated Products

MAX5160LEUA+ Frequently Asked Questions (FAQs)

• What is the recommended layout and routing for the MAX5160LEUA+ to minimize noise and ensure optimal performance?
  To minimize noise and ensure optimal performance, it is recommended to follow a star-grounding scheme, keep analog and digital grounds separate, and use a solid ground plane. Additionally, keep the input and output traces short and away from noise sources, and use a low-ESR capacitor for the output filter.
• How do I choose the right output filter components for the MAX5160LEUA+?
  The output filter components should be chosen based on the desired output voltage ripple and load current. A good starting point is to use a 10uF ceramic capacitor and a 1uH inductor. The datasheet provides a formula to calculate the output filter components based on the desired output voltage ripple and load current.
• What is the maximum input voltage that the MAX5160LEUA+ can handle?
  The MAX5160LEUA+ can handle an input voltage up to 42V, but it is recommended to operate within the specified input voltage range of 4.5V to 36V for optimal performance and reliability.
• How do I implement overcurrent protection with the MAX5160LEUA+?
  The MAX5160LEUA+ has a built-in overcurrent protection feature that can be enabled by connecting the OCSET pin to a resistor divider network. The resistor values should be chosen based on the desired overcurrent threshold and the output voltage.
• What is the thermal derating curve for the MAX5160LEUA+?
  The thermal derating curve for the MAX5160LEUA+ is not explicitly provided in the datasheet, but it can be estimated based on the package thermal resistance and the maximum junction temperature. A good rule of thumb is to derate the output current by 1% for every 1°C increase in ambient temperature above 25°C.
