DC Switching Voltage Regulators

TL7660IDR Description

The TL7660IDR from Texas Instruments is a charge pump voltage inverter IC designed to generate a negative output voltage from a positive input supply. Housed in an 8-SOIC package with tape-and-reel (TR) packaging, it operates over a wide input voltage range of 1.5V to 10V, making it versatile for various low-power applications. This fixed-output, ratiometric charge pump delivers efficient voltage inversion with a switching frequency of 10kHz, eliminating the need for an external inductor. Its single-output configuration supports both positive and negative voltage conversion, simplifying circuit design while maintaining compactness.
