• Manufacturer: Epson Electronics America, Inc.

S1F76540 Series Charge Pumping DC/DC Converter &
Voltage Regulator
DESCRIPTION
The S1F76540C0A0/M0A0 is a CMOS process,
charge-pumping DC/DC converter and voltage regula-
tor featuring the very high efficiency but low power
consumption. An addition of four, three, or two exter-
nal capacitors can generate four-, three- or two-time
output voltage in negative direction than the input volt-
age. Also, the built-in voltage regulator can set any out-
put voltage of DC/DC converter and can output the
regulated voltage using two external resistances. As the
regulator output can have a negative temperature gradi-
ent that is required for LCD panels, it is optimum for the
LCD panel power supply.
