TPS54201DDCR datasheet by Texas Instruments

TPS54201DDCR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS54201DDCR?
  The maximum input voltage that can be applied to the TPS54201DDCR 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 calculate the output voltage of the TPS54201DDCR?
  The output voltage of the TPS54201DDCR can be calculated using the following formula: Vout = 0.8V x (1 + R1/R2), where R1 and R2 are the resistors connected to the FB (feedback) pin.
• What is the maximum output current that the TPS54201DDCR can deliver?
  The maximum output current that the TPS54201DDCR can deliver is 2A, but it's recommended to keep it below 1.5A for reliable operation.
