TL7660CDGKR Charge Pump Voltage Converter by Texas Instruments

The TL7660CDGKR is a versatile voltage converter integrated circuit (IC) from the renowned semiconductor manufacturer Texas Instruments. This compact and efficient IC is designed to provide a reliable solution for applications requiring voltage inversion from a positive to a negative supply. It is a member of the charge pump voltage converter family, which utilizes switched capacitor technology to achieve voltage conversion without the need for an inductor, thereby simplifying design and reducing component count.

Encased in an 8-pin VSSOP (Very Small Shrink Outline Package), the TL7660CDGKR offers a space-saving footprint on printed circuit boards (PCBs), making it an excellent choice for portable and space-constrained applications. The device operates over a wide input voltage range from 1.5V to 10V, allowing it to be powered by a variety of sources, including standard batteries and regulated power supplies.

One of the key features of the TL7660CDGKR is its ability to provide a stable output voltage with a high efficiency. The device is capable of delivering an output current up to 20mA (typical) with a voltage conversion efficiency that is maintained over a wide range of load conditions. This makes it suitable for powering small, low-power circuits such as operational amplifiers, data converters, and microcontrollers in a negative supply configuration.

Additional features of the TL7660CDGKR include low power consumption, which is critical for battery-powered devices, and an onboard oscillator that eliminates the need for external frequency-setting components. The IC also includes over-temperature protection, ensuring reliable operation under varying environmental conditions.

Applications for the TL7660CDGKR are diverse and include handheld instrumentation, portable medical devices, battery-powered equipment, and any system that requires a negative voltage rail for operational purposes. Its ease of use, combined with Texas Instruments' reputation for quality and reliability, makes the TL7660CDGKR a go-to choice for engineers and designers looking to implement a negative voltage supply in their electronic designs.
