TPS51020DBTG4 datasheet by Texas Instruments

TPS51020DBTG4 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS51020DBTG4?
  The maximum input voltage that can be applied to the TPS51020DBTG4 is 18V, but it's recommended to keep it below 15V for reliable operation.
• How do I ensure the TPS51020DBTG4 is stable and doesn't oscillate?
  To ensure stability, make sure to follow the recommended layout and component placement guidelines, use a sufficient output capacitor (at least 10uF), and add a 1uF capacitor between the VIN and EN pins.
• What is the minimum input voltage required for the TPS51020DBTG4 to operate?
  The minimum input voltage required for the TPS51020DBTG4 to operate is 6.5V, but it's recommended to keep it above 7V for reliable startup.
• Can I use the TPS51020DBTG4 in a high-temperature environment?
  The TPS51020DBTG4 is rated for operation up to 125°C, but its performance and reliability may degrade at high temperatures. Make sure to follow the recommended operating conditions and derate the output current accordingly.
• How do I calculate the output voltage of the TPS51020DBTG4?
  The output voltage of the TPS51020DBTG4 can be calculated using the formula: VOUT = 0.8V x (1 + R1/R2), where R1 and R2 are the resistors connected to the FB pin.
