UCD3028RHAR datasheet by Texas Instruments

UCD3028RHAR Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for the UCD3028RHAR?
  Texas Instruments provides a recommended PCB layout in the UCD3028RHAR evaluation module (EVM) user's guide, which includes guidelines for component placement, routing, and thermal management.
• How do I optimize the UCD3028RHAR for low power consumption?
  To optimize the UCD3028RHAR for low power consumption, use the Power Save Mode (PSM) feature, reduce the switching frequency, and minimize the number of active phases. Additionally, ensure that the input voltage is within the recommended range and use a high-efficiency output filter.
• What is the maximum output current capability of the UCD3028RHAR?
  The maximum output current capability of the UCD3028RHAR depends on the specific application and the number of active phases. However, the device is designed to support up to 20A per phase, and the total output current can be scaled up to 80A or more by paralleling multiple phases.
• How do I troubleshoot issues with the UCD3028RHAR, such as over-temperature or over-current faults?
  To troubleshoot issues with the UCD3028RHAR, use the device's built-in fault monitoring and reporting features, such as the Fault pin and the I2C interface. Additionally, use oscilloscopes and current probes to monitor the device's input and output waveforms and currents.
• Can I use the UCD3028RHAR in a non-isolated DC-DC converter design?
  Yes, the UCD3028RHAR can be used in non-isolated DC-DC converter designs, such as buck, boost, or buck-boost converters. However, the device's high-side and low-side FET drivers must be configured accordingly, and the output voltage and current ratings must be within the device's specifications.
