DS3691MX Frequently Asked Questions (FAQs)

• What is the recommended layout and routing for the DS3691MX?
  Texas Instruments provides a recommended layout and routing guide in the DS3691MX datasheet, application notes, and evaluation module documentation. It's essential to follow these guidelines to ensure proper operation, minimize noise, and reduce electromagnetic interference (EMI).
• How do I select the correct input capacitor values for the DS3691MX?
  The input capacitor values depend on the input voltage, output voltage, and desired output ripple. TI provides a capacitor selection guide in the datasheet and application notes. Additionally, online calculators and simulation tools can help determine the optimal capacitor values.
• What is the maximum output current capability of the DS3691MX?
  The maximum output current capability of the DS3691MX is 1.5 A. However, the actual output current depends on the input voltage, output voltage, and thermal conditions. It's essential to ensure the device operates within the recommended operating conditions to avoid overheating and damage.
• How do I implement overcurrent protection with the DS3691MX?
  The DS3691MX has a built-in overcurrent protection feature that can be enabled by connecting the OCSET pin to a resistor divider network. This sets the overcurrent threshold. When the output current exceeds the set threshold, the device will enter a shutdown state to protect itself and the load.
• What is the purpose of the EN pin on the DS3691MX, and how do I use it?
  The EN (enable) pin is used to enable or disable the DS3691MX. When the EN pin is pulled high, the device is enabled, and when it's pulled low, the device is disabled. This pin can be used to implement power sequencing, shutdown, or low-power modes in the system.
