TPS3828-33DBVT datasheet by Texas Instruments

TPS3828-33DBVT Frequently Asked Questions (FAQs)

• What is the recommended layout and placement for the TPS3828-33DBVT?
  The recommended layout and placement for the TPS3828-33DBVT 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 'TPS3828 Layout and Placement Guidelines' for more information.
• How do I ensure the TPS3828-33DBVT 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 TPS3828-33DBVT can handle?
  The TPS3828-33DBVT can handle a maximum input voltage of 18V, but it is recommended to operate within the recommended input voltage range of 2.7V to 15V for optimal performance and reliability.
• Can I use the TPS3828-33DBVT in a high-temperature environment?
  The TPS3828-33DBVT is rated for operation up to 125°C, but the device's performance and reliability may degrade at high temperatures. It is recommended to operate the device within the recommended operating temperature range of -40°C to 85°C for optimal performance and reliability.
• How do I calculate the output voltage of the TPS3828-33DBVT?
  The output voltage of the TPS3828-33DBVT is fixed at 3.3V and is determined by the internal voltage reference. No external resistors or voltage-setting components are required.
