LM2662 Datasheet (Texas Instruments) - Switched Capacitor Voltage Converter

LM2662, Switched Capacitor Voltage Converter

The LM2662/LM2663 CMOS charge-pump voltage converter inverts a positive voltage in the range of 1.5 V to 5.5 V to the corresponding negative voltage.

The LM2662/LM2663 uses two low cost capacitors to provide 200 mA of output current without the cost, size, and EMI related to inductor based converter
