LM2767 February 2000 Switched LM2767Switched Capacitor Voltage ConverterGeneral Description Features The LM2767 CMOS charge-pump voltage converter oper- n Doubles Input Supply Voltage Capacitor ates as a voltage doubler for an input voltage in the range of n SOT23-5 Package +1.8V to +5.5V. Two low cost capacitors and a diode are n 20 Typical Output Impedance used in this circuit to provide at least 15 mA of output current. n 96% Typical Conversion Efficiency at 15mA The LM2767 operates at 11 kHz switching frequency toavoid audio voice-band interference. With an operating cur- Applications rent of only 40 µA (operating efficiency greater than 90% with n Cellular Phones most loads), the LM2767 provides ideal performance for V battery powered systems. The device is manufactured in a n Pagers oltage SOT23-5 package. n PDAs, Organizers n Operational Amplifier Power Suppliers n Interface Power Suppliers n Handheld Instruments Converter Basic Application Circuit Voltage Doubler 10127401 Ordering Information Order Number Package Number Package Marking Supplied as LM2767M5 MA05B S17B (Note 1) Tape and Reel (1000 units/reel) LM2767M5X MA05B S17B (Note 1) Tape and Reel (3000 units/reel) Note 1: The small physical size of the SOT-23 package does not allow for the full part number marking.
