9 Power Supply Recommendations

The TPS54116-Q1 is designed to be powered by a well regulated dc voltage between 2.95 and 6 V. The TPS54116-Q1 is a buck converter so the input supply voltage must be greater than the desired output voltage to regulate the output voltage to the desired value. If the input supply voltage is not high enough the output voltage will begin to drop. Input supply current must be appropriate for the desired output current.
