TPS54260DGQR datasheet by Texas Instruments

TPS54260DGQR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS54260DGQR?
  The maximum input voltage that can be applied to the TPS54260DGQR is 42V, but it's recommended to keep it below 40V for reliable operation.
• How do I ensure the stability of the output voltage?
  To ensure the stability of the output voltage, it's essential to use a suitable output capacitor with a low equivalent series resistance (ESR) and a sufficient capacitance value. A 10uF to 22uF ceramic capacitor is recommended.
• What is the purpose of the EN pin, and how do I use it?
  The EN (enable) pin is used to turn the regulator on or off. To turn the regulator on, connect the EN pin to VIN or a logic high signal. To turn it off, connect the EN pin to GND or a logic low signal.
• How do I adjust the output voltage of the TPS54260DGQR?
  The output voltage of the TPS54260DGQR can be adjusted by using a resistor divider network between the output and the ADJ pin. The output voltage is determined by the ratio of the resistors and the internal reference voltage.
• What is the maximum output current that the TPS54260DGQR can deliver?
  The maximum output current that the TPS54260DGQR can deliver is 2A, but it's recommended to keep it below 1.5A for reliable operation and to prevent overheating.
