LM3350 - Switched Capacitor Voltage Converter
The LM3350 is a CMOS charge-pump voltage converter which efficiently provides a 3.3V to 5V step-up, or 5V to 3.3V step-down.
The LM3350 uses four small, low cost capacitors to provide the voltage conversion.
It eliminates the cost, size and radiated EMI related to inductor based circuits, or the pow
