The maximum input voltage that can be applied to the TPS54260QDGQRQ1 is 42V, but it's recommended to operate within the specified input voltage range of 4.5V to 38V for optimal performance and reliability.
To ensure the stability of the output voltage, it's essential to follow the recommended layout guidelines, use a suitable output capacitor, and ensure that the input voltage is within the specified range. Additionally, the output voltage can be adjusted using the FB pin, and the output voltage tolerance can be set using the EN pin.
The maximum output current that the TPS54260QDGQRQ1 can deliver is 2A, but it's recommended to operate within the specified output current range of 0A to 1.5A for optimal performance and reliability.
To protect the TPS54260QDGQRQ1 from overheating, it's essential to ensure good thermal design, use a suitable heat sink, and operate within the specified temperature range of -40°C to 125°C. Additionally, the device has built-in thermal shutdown protection that will turn off the device if the junction temperature exceeds 150°C.
The EN (enable) pin is used to enable or disable the device. When the EN pin is high, the device is enabled, and when it's low, the device is disabled. The EN pin can be used to implement power sequencing, shutdown, or low-power modes in the system.
