LM2682
Switched Capacitor Voltage Doubling Inverter
General DescriptionThe LM2682isa CMOS charge-pump voltage inverter ca-
pableof converting positive voltageinthe rangeof +2.0Vto
+5.5Vto the corresponding doubled negative voltageof
−4.0Vto −11.0V respectively. The LM2682 uses three low
cost capacitorsto provide10 mAof output current without
the cost, size, and EMI relatedto inductor based circuits.
Withan operating currentof only 150µA andan operating
efficiency greater than 90% with most loads, the LM2682
provides ideal performancefor battery powered systems.
The LM2682 offersa switching frequencyof6 kHz.
Features Inverts then doubles input supply voltage Small MSOP-8 package (mini SO-8) and SO-8 package 90Ω typical output impedance 94% typical power efficiencyat10 mA
