TPS68000DBTR datasheet by Texas Instruments

TPS68000DBTR Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  A 2-layer or 4-layer PCB with a solid ground plane and thermal vias is recommended. Keep the thermal pad connected to the ground plane to improve heat dissipation.
• How do I ensure the device operates within the recommended operating conditions?
  Monitor the input voltage, output voltage, and output current to ensure they are within the specified ranges. Also, ensure the device is operated within the recommended temperature range of -40°C to 125°C.
• What is the recommended input capacitor type and value for the TPS68000DBTR?
  A low-ESR ceramic capacitor with a value of 10uF to 22uF is recommended for the input capacitor. This helps to filter out noise and improve the power supply's stability.
• How do I calculate the output voltage ripple for the TPS68000DBTR?
  The output voltage ripple can be calculated using the formula: ΔVout = (Iout * Rl) / (f * Cout), where Iout is the output current, Rl is the load resistance, f is the switching frequency, and Cout is the output capacitor value.
• What is the recommended output capacitor type and value for the TPS68000DBTR?
  A low-ESR ceramic capacitor with a value of 10uF to 22uF is recommended for the output capacitor. This helps to filter out noise and improve the power supply's stability.
