TPS3840DL19DBVR Frequently Asked Questions (FAQs)

  • The recommended layout and placement for the TPS3840DL19DBVR involves placing the device close to the power source, using a solid ground plane, and keeping the input and output traces short and wide. Additionally, it's recommended to place a 10uF ceramic capacitor between the VIN and GND pins, and a 1uF ceramic capacitor between the VOUT and GND pins.
  • The output voltage of the TPS3840DL19DBVR can be adjusted by connecting a resistor divider network between the VOUT pin and the GND pin, and connecting the center tap of the divider to the FB pin. The output voltage can be calculated using the formula: VOUT = 0.8V x (R1 + R2) / R2, where R1 and R2 are the resistors in the divider network.
  • The maximum input voltage that the TPS3840DL19DBVR can handle is 18V. Exceeding this voltage may cause damage to the device.
  • The TPS3840DL19DBVR can be enabled and disabled by applying a logic signal to the EN pin. A high logic level (above 1.4V) enables the device, while a low logic level (below 0.4V) disables it.
  • The typical startup time of the TPS3840DL19DBVR is around 1ms, but this can vary depending on the input voltage, output voltage, and load current.
