The TL7660IDGKR from Texas Instruments is a CMOS switched-capacitor voltage converter designed for efficient supply-voltage conversions from positive to negative. This device requires only two external, noncritical capacitors for its charge pump and charge reservoir functions. It accepts an input voltage range of 1.5 V to 10 V and generates a complementary negative output voltage from -1.5 V to -10 V.
This voltage converter can also be configured as a voltage doubler, capable of producing output voltages up to 18.6 V when supplied with a 10-V input. Key electrical characteristics include a typical open-circuit voltage conversion efficiency of 99.9% and a typical power efficiency of 98%. The device operates over a wide temperature range of -40°C to 125°C.
Packaged in an 8-VSSOP, the TL7660IDGKR is suitable for surface mount applications. Its design is based on building blocks including a linear regulator, an RC oscillator, and a voltage-level translator, making it a versatile component for various power management needs.
Applications for the TL7660IDGKR include on-board negative supplies, data-acquisition systems, and portable electronics where efficient and compact voltage conversion is required.
