TPS79933DDCRG4 Frequently Asked Questions (FAQs)

  • Texas Instruments provides a recommended PCB layout in the TPS79933 datasheet (SLVSAB4) and in the TPS79933 Evaluation Module User's Guide (SLVUAE4). It's essential to follow these guidelines to minimize noise, ensure stability, and achieve optimal performance.
  • The output capacitor selection depends on the output voltage, output current, and desired transient response. TI recommends using a low-ESR ceramic capacitor with a value between 1 μF and 10 μF. A higher capacitance value can improve transient response, but may increase the startup time.
  • The TPS79933 has an absolute maximum input voltage rating of 6.5 V. However, the recommended operating input voltage range is 2.7 V to 5.5 V. Exceeding the absolute maximum rating can damage the device.
  • The TPS79933 is rated for operation up to 125°C (TJ). However, the device's performance and reliability may degrade at high temperatures. It's essential to consider the thermal design and ensure proper heat dissipation to maintain optimal performance.
  • To ensure stability, follow the recommended PCB layout, use a suitable output capacitor, and ensure the input voltage is within the recommended range. Additionally, adding a small ceramic capacitor (e.g., 10 nF) between the VIN and GND pins can help improve stability.
