TPS3820-33DBVRG4 datasheet by Texas Instruments

TPS3820-33DBVRG4 Frequently Asked Questions (FAQs)

• What is the recommended layout and placement for the TPS3820-33DBVRG4?
  The recommended layout and placement for the TPS3820-33DBVRG4 involves placing the device close to the power source, using a solid ground plane, and keeping the input and output capacitors close to the device. A 4-layer PCB with a solid ground plane is recommended. Refer to the TI application note 'TPS3820 Layout and Placement Guidelines' for more information.
• How do I ensure the TPS3820-33DBVRG4 is stable and does not oscillate?
  To ensure stability, follow the recommended layout and placement guidelines, use a minimum of 1uF ceramic capacitor at the input and output, and ensure the output capacitor has a low ESR. Additionally, the device has a built-in compensation network, so no external compensation is required.
• What is the maximum input voltage that the TPS3820-33DBVRG4 can handle?
  The TPS3820-33DBVRG4 can handle a maximum input voltage of 18V, but it is recommended to operate within the specified operating range of 2.7V to 15V for optimal performance and reliability.
• Can I use the TPS3820-33DBVRG4 in a high-temperature environment?
  The TPS3820-33DBVRG4 is rated for operation up to 125°C, but the device's performance and reliability may degrade at high temperatures. It is recommended to derate the device's output current and voltage according to the temperature derating curve in the datasheet.
• How do I calculate the output voltage of the TPS3820-33DBVRG4?
  The output voltage of the TPS3820-33DBVRG4 is fixed at 3.3V and is not adjustable. The device is designed to provide a regulated 3.3V output voltage from a wide range of input voltages.
