TC7660 Charge Pump DC to DC Voltage Converter IC
The TC7660 is a charge pump DC-to-DC voltage converter IC that facilitates voltage inversion or negative voltage generation in compact and efficient designs. This IC is particularly well-suited for applications requiring a straightforward solution for creating negative voltage rails from a positive supply, such as in analog signal processing, operational amplifier circuits, and portable electronics. Utilizing a switched-capacitor approach, the TC7660 operates without inductors, significantly simplifying circuit design and reducing component count. Operating over an input voltage range of +1.5V to +10V, the TC7660 can produce a negative output that closely mirrors the input voltage. With a typical efficiency of up to 98%, it is power-efficient and minimizes energy loss, which is crucial for battery-powered devices. It features a low quiescent current draw, typically around 80 µA, ensuring minimal power consumption during idle periods. The IC also incorporates an internal oscillator and voltage regulation circuitry, providing stable performance without requiring complex external components.
