The LMR16006 is designed to operate from an input voltage supply range between 4 V and 60 V. This input supply should be able to withstand the maximum input current and maintain a voltage above 4 V. The resistance of the input supply rail should be low enough that an input current transient does not cause a high enough drop at the LMR16006 supply voltage that can cause a false UVLO fault triggering and system reset. If the input supply is located more than a few inches from the LMR16006, additional bulk capacitance may be required in addition to the ceramic input capacitors.
