TPS40000DGQ Frequently Asked Questions (FAQs)

  • Texas Instruments provides a recommended PCB layout in the TPS40000DGQ datasheet (Section 10.2) and in the TPS40000DGQ Evaluation Module User's Guide (SLUU444). It's essential to follow these guidelines to minimize noise, ensure proper thermal management, and optimize performance.
  • The input capacitor selection depends on the input voltage, current, and frequency. TI recommends using low-ESR capacitors with a minimum capacitance of 10uF and a voltage rating of at least 1.5 times the maximum input voltage. Refer to the TPS40000DGQ datasheet (Section 7.3) for more information.
  • The TPS40000DGQ can deliver up to 4A of output current per phase, but the maximum current capability depends on the thermal design and the application's requirements. It's essential to consider the thermal constraints and ensure proper heat sinking to achieve the desired output current.
  • The TPS40000DGQ output voltage can be configured using the VSENSE pin and an external resistor divider network. The datasheet (Section 7.4) provides a formula to calculate the required resistor values for a specific output voltage.
  • The PG (Power Good) pin is an open-drain output that indicates when the output voltage is within the specified regulation range. It can be used to enable or disable downstream circuits or to generate a reset signal. The PG pin can be connected to a pull-up resistor and a logic input or used to drive an external circuit.
