TPS40003DGQ Frequently Asked Questions (FAQ)

  • Texas Instruments provides a recommended PCB layout in the TPS40003DGQ evaluation module documentation, which includes guidelines for component placement, trace routing, and thermal management to ensure optimal performance and minimize noise.

  • The selection of input and output capacitors depends on the specific requirements of your application, including the input voltage range, output voltage, and desired ripple and noise performance. TI provides guidance on capacitor selection in the TPS40003DGQ datasheet and application notes.

  • The TPS40003DGQ has a maximum ambient temperature rating of 85°C, but the device can operate at higher temperatures with derating. Refer to the datasheet for thermal derating curves and guidelines for operation in high-temperature environments.

  • The TPS40003DGQ has a built-in overcurrent protection feature that can be enabled by connecting a resistor between the OCSET pin and the output voltage. The value of the resistor determines the overcurrent threshold. TI provides guidance on overcurrent protection implementation in the datasheet and application notes.

  • The recommended startup sequence for the TPS40003DGQ is to first apply the input voltage, then enable the device by pulling the EN pin high. This ensures that the device starts up correctly and avoids any potential issues with the output voltage.
