TPS3620-33DGKT datasheet by Texas Instruments

TPS3620-33DGKT Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for the TPS3620-33DGKT to ensure optimal performance?
  A good PCB layout for the TPS3620-33DGKT involves placing the input capacitor close to the VIN pin, and the output capacitor close to the VOUT pin. Additionally, the GND pin should be connected to a solid ground plane to reduce noise and improve stability.
• How do I ensure the TPS3620-33DGKT is stable and doesn't oscillate?
  To ensure stability, make sure the output capacitor has a low ESR (Equivalent Series Resistance) and is placed close to the VOUT pin. Also, the input capacitor should be placed close to the VIN pin and have a value between 1uF to 10uF. Finally, ensure the PCB layout is well-designed to minimize noise and parasitic inductance.
• What is the maximum input voltage that the TPS3620-33DGKT can handle?
  The TPS3620-33DGKT can handle input voltages up to 15V, but it's recommended to keep the input voltage below 12V for optimal performance and reliability.
• Can I use the TPS3620-33DGKT in a high-temperature environment?
  The TPS3620-33DGKT is rated for operation up to 125°C, but its performance may degrade at high temperatures. It's recommended to derate the output current and ensure good thermal design to prevent overheating.
• How do I calculate the output voltage of the TPS3620-33DGKT?
  The output voltage of the TPS3620-33DGKT is fixed at 3.3V and is not adjustable. The internal voltage reference and feedback network ensure a stable output voltage.
