TPS3823-25DBVR datasheet by Texas Instruments

TPS3823-25DBVR Frequently Asked Questions (FAQs)

• What is the recommended layout and placement for the TPS3823-25DBVR?
  The recommended layout and placement for the TPS3823-25DBVR 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 good layout practice is to use a star connection for the power and ground pins to minimize noise and ensure proper operation.
• How do I ensure the TPS3823-25DBVR is stable and does not oscillate?
  To ensure stability, it is essential to follow the recommended component values and layout guidelines. Additionally, the output capacitor should be selected based on the output voltage and current requirements. A minimum output capacitance of 10uF is recommended, and the capacitor should be placed close to the device.
• What is the maximum input voltage that the TPS3823-25DBVR can handle?
  The TPS3823-25DBVR can handle input voltages up to 40V, but it is recommended to operate within the specified input voltage range of 2.7V to 38V for optimal performance and reliability.
• Can I use the TPS3823-25DBVR in a high-temperature environment?
  The TPS3823-25DBVR is rated for operation up to 125°C, but it is essential to consider the thermal design and ensure proper heat dissipation to prevent overheating. A thermal pad is available on the device to help with heat dissipation.
• How do I adjust the output voltage of the TPS3823-25DBVR?
  The output voltage of the TPS3823-25DBVR can be adjusted by using a resistive divider network between the output and the feedback pin. The output voltage can be calculated using the formula: Vout = 2.5V x (R1 + R2) / R2.
