LM2776DBVT Description
The LM2776 CMos charge-pump voltage converterinverts a positive voltage in the range of 2.7 V to 5.5v to the corresponding negative voltage.The LM2776uses three low-cost capacitors to provide 2oo mA ofoutput current without thecost,size, andelectromagneticinterference(EMIrelated toinductor-based converters.
With an operating current of only 100 uAandoperating efficiency greater than 90 %at most loads,the LM2776 provides ideal performance for battery-powered systems requiring 'a high power negativepower supply. The LM2776 has been placed in TI's 6-pin sOT-23 tomaintain a small form factor.
