The maximum input voltage that can be applied to the TPS54540BQDDAQ1 is 42V, but it's recommended to operate within the specified input voltage range of 6.5V to 36V for optimal performance and reliability.
To ensure the stability of the output voltage, it's essential to follow the recommended layout and component selection guidelines provided in the datasheet, including the use of a suitable output capacitor and input filter components.
The TPS54540BQDDAQ1 can deliver up to 4A of output current, but the actual output current capability may be limited by the input voltage, output voltage, and thermal considerations.
The output voltage of the TPS54540BQDDAQ1 can be adjusted by using an external resistor divider network connected to the FB pin, as described in the datasheet.
The EN (enable) pin is used to enable or disable the device. When the EN pin is pulled low, the device is in shutdown mode, and when it's pulled high, the device is enabled and operates normally.
