TPS3828-33DBVTG4 datasheet by Texas Instruments

TPS3828-33DBVTG4 Frequently Asked Questions (FAQs)

• What is the recommended layout and placement for the TPS3828-33DBVTG4?
  The recommended layout and placement for the TPS3828-33DBVTG4 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 Texas Instruments application note 'TPS3828 Layout and Placement Guidelines' for more information.
• How do I ensure the TPS3828-33DBVTG4 is stable and does not oscillate?
  To ensure stability, it is essential to follow the recommended layout and placement guidelines, use a sufficient output capacitor with a low ESR, and add a 10nF capacitor between the VREF and GND pins. Additionally, the input capacitor should be placed close to the device and have a low ESR. A minimum of 1uF input capacitance is recommended.
• What is the maximum input voltage that the TPS3828-33DBVTG4 can handle?
  The TPS3828-33DBVTG4 can handle a maximum input voltage of 18V. However, it is recommended to operate the device within the specified input voltage range of 2.7V to 18V for optimal performance and reliability.
• Can I use the TPS3828-33DBVTG4 in a high-temperature environment?
  The TPS3828-33DBVTG4 is rated for operation up to 125°C. However, the device's performance and reliability may degrade at high temperatures. It is essential to follow the recommended operating conditions and derate the device's performance accordingly.
• How do I calculate the output voltage of the TPS3828-33DBVTG4?
  The output voltage of the TPS3828-33DBVTG4 can be calculated using the formula: VOUT = VREF x (1 + R1/R2), where VREF is the internal reference voltage (3.3V), and R1 and R2 are the resistors connected to the FB pin.
