Texas Instruments LM2776DBVT
The LM2776 CMOS charge-pump voltage converter inverts a positive voltage in the rangefrom 2.7 V to 5.5 V to the corresponding negative voltage. The LM2776 uses three low-costcapacitors to provide 200 mA of output current without the cost, size, and electromagneticinterference (EMI) related to inductor-based converters.
With an operating current of only 100 µA and operating efficiency greater than 90% atmost loads, the LM2776 provides ideal performance for battery-powered systems requiring a highpower negative power supply.
The LM2776 has been placed in TIs 6-pin SOT-23 to maintain a small formfactor.
