LM2767
- Doubles input supply voltage
- SOT-23 5-pin package
- 20-Ω typical output impedance
- 96% typical conversion efficiency at 15 mA
The LM2767 CMOS charge-pump voltage converter operates as a voltage doubler for an input voltage in the range of 1.8 V to 5.5 V. Two low-cost capacitors and a diode are used in this circuit to provide at least 15 mA of output current.
The LM2767 operates at 11-kHz switching frequency to avoid audio voice-band interference. With an operating current of only 40 µA (operating efficiency greater than 90% with most loads), the LM2767 provides ideal performance for battery-powered systems. The device is manufactured in a 5-pin SOT-23 package.
