The Texas Instruments LM2664 is a versatile CMOS charge-pump voltage converter designed to invert a positive input supply voltage into a corresponding negative output voltage. It operates with an input voltage range of 1.8 V to 5.5 V, providing an output voltage range of -1.8 V to -5.5 V. This device is capable of delivering up to 40 mA of output current, utilizing two low-cost external capacitors.
The LM2664 features a typical output impedance of 12 Ω and achieves a high conversion efficiency of 91% at 40 mA. Its low operating current of 220 µA and a typical shutdown current of 1 µA make it an ideal choice for power-sensitive, battery-powered systems. The device operates at a 160-kHz oscillator frequency, which helps in reducing output resistance and voltage ripple.
Packaged in a compact 6-pin SOT-23 surface-mount package, the LM2664 is designed for ease of integration into various electronic designs. Its features, including an enable pin and unregulated output, offer flexibility in system design. The operating temperature range is from -40°C to 85°C.
