9 Power Supply Recommendations
The LM3269 device is designed to operate from an input voltage supply range between 2.7 V and 5.5 V. This
input supply should be well regulated. If the input supply is located more than a few inches from the LM3269
converter additional bulk capacitance may be required in addition to the ceramic bypass capacitors. An
electrolytic or tantalum capacitor with a value of 47 μF is a typical choice.
