TPS3780ADRYR datasheet by Texas Instruments

TPS3780ADRYR Frequently Asked Questions (FAQs)

• What is the recommended layout and placement for the TPS3780ADRYR?
  The recommended layout and placement for the TPS3780ADRYR 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. Additionally, it is recommended to use a Kelvin connection for the sense pins to minimize noise and ensure accurate voltage sensing.
• How do I handle the power-up sequence for the TPS3780ADRYR?
  The power-up sequence for the TPS3780ADRYR involves applying the input voltage (VIN) before the enable signal (EN). The device will then power up and regulate the output voltage. It is recommended to use a soft-start circuit to control the power-up sequence and prevent inrush currents.
• What is the maximum input voltage that the TPS3780ADRYR can handle?
  The maximum input voltage that the TPS3780ADRYR can handle is 6.5V, although the recommended maximum input voltage is 5.5V to ensure reliable operation and prevent damage to the device.
• How do I adjust the output voltage of the TPS3780ADRYR?
  The output voltage of the TPS3780ADRYR can be adjusted by connecting a resistive divider network between the output voltage (VOUT) and the sense pins (SENSE+ and SENSE-). The resistive divider network sets the output voltage based on the desired voltage and the internal reference voltage of the device.
• What is the purpose of the power-good (PG) output pin on the TPS3780ADRYR?
  The power-good (PG) output pin on the TPS3780ADRYR is an open-drain output that indicates when the output voltage is within the specified regulation range. The PG pin can be used to monitor the output voltage and provide a signal to the system when the output voltage is valid.
