UCD9248PFCR Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane, separate power and ground planes for the analog and digital sections, and a star-configuration for the power supply connections is recommended. Additionally, keep the switching nodes (SW and BST) away from sensitive analog nodes.
  • Use the TI Power Stage Designer tool to generate a compensation network based on the specific application requirements. The tool provides a suggested compensation network based on the input voltage, output voltage, and switching frequency.
  • The maximum allowed input voltage for the UCD9248PFCR is 24V. Exceeding this voltage may damage the device.
  • Implement a proper thermal design, including a heat sink and thermal interface material, to keep the junction temperature below 125°C. Monitor the device temperature using the internal thermal monitoring feature or an external temperature sensor.
  • The EN (Enable) pin is used to enable or disable the device. Connect the EN pin to a logic-level signal (e.g., from a microcontroller) to control the device's operation. When EN is low, the device is disabled, and when EN is high, the device is enabled.
