9 Power Supply Recommendations

The TPS92613-Q1 is designed to operate from an automobile electrical power system within the range specified in the Recommended Operating Conditions. The V(SUPPLY) input must be protected from reverse voltage and voltage dump condition over 40 V. The impedance of the input supply rail must be low enough that the input current transient does not cause drop below LED string required forward voltage. If the input supply is connected with long wires, additional bulk capacitance may be required in addition to normal input capacitor.
