LM2776 Datasheet (Texas Instruments) - Switched Capacitor Inverter

LM2776, Switched Capacitor Inverter

The LM2776 CMOS charge-pump voltage converter inverts a positive voltage in the range from 2.7 V to 5.5 V to the corresponding negative voltage.

The LM2776 uses three low-cost capacitors to provide 200 mA of output current without the cost, size, and electromagnetic interference (EMI) related to ind
