SNVSA56B – MAY 2015 – REVISED FEBRUARY 2017 LM2776 Switched Capacitor Inverter
1 Features 3 Description 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
inductor-based converters. 1 Input Voltage: 2.7 V to 5.5 V
