9 Power Supply Recommendations

TPS563231 is designed to operate from input supply voltage in the range of 4.5 V to 17 V. Buck converters require the input voltage to be higher than the output voltage for proper operation. The maximum recommended operating duty cycle is 72%. Using that criteria, the minimum recommended input voltage is VO / 0.72.
