What are the key features of TL7660IDRG4?
- Voltage inversion from 1.5 V to 10 V input delivers a mirrored negative rail (-1.5 V to -10 V) using only 2 external capacitors, simplifying dual-supply generation
- Step-up and step-down switching modes provide flexible output ranging from negative rail to doubled positive voltage, adapting to diverse power architecture requirements
- 8-pin SOIC package with inductor-free switched-capacitor topology minimizes PCB area and eliminates magnetic EMI concerns in noise-sensitive analog circuits
What is TL7660IDRG4 used for?
The TL7660IDRG4 is commonly used to generate a negative supply rail from a single positive input in op-amp circuits, LCD bias generators, and RS-232 transceiver power rails where a negative voltage is required but only a single positive supply is available. Its 1.5 V minimum input voltage suits low-dropout regulator outputs and battery-powered systems needing dual-supply analog stages without a separate DC-DC converter. Portable test equipment, audio preamplifiers, and sensor signal conditioning boards benefit from its compact 8-pin SOIC form and inductor-free design.

Frequently Asked Questions
What input voltage range does TL7660IDRG4 accept and what output voltages can it produce?
TL7660IDRG4 operates from a 1.5 V to 10 V input and produces an inverted output ranging from -1.5 V to -10 V. When configured for voltage doubling, the output can reach up to 20 V from a 10 V input. This versatility covers single-cell Li-Ion systems at 3.7 V, 5 V logic supplies, and 9 V or 10 V instrument rails.
How many external components does TL7660IDRG4 require to generate a negative voltage rail?
In a basic voltage inversion configuration, TL7660IDRG4 requires only 2 external capacitors—a charge pump capacitor (typically 10 µF) connected between the OSC and CAP+ pins, and an output filter capacitor (also typically 10 µF) at the output. This minimal BOM of 2 capacitors and the 8-pin SOIC IC makes it an extremely compact and cost-effective solution compared to inductor-based inverting converters.
In which single-supply op-amp circuit scenarios does TL7660IDRG4 provide the most value?
TL7660IDRG4 excels when a precision op-amp requires dual ±5 V supplies but only a 5 V single supply is available. By inverting the 5 V rail, it creates a -5 V supply with minimal external components. This is particularly useful in audio signal chains, sensor front-ends, and active filter stages where rail-to-rail signal swing is needed and adding a separate negative regulator or transformer would be impractical.
What oscillator frequency does TL7660IDRG4 use for charge pumping and can it be adjusted?
TL7660IDRG4 has an internal oscillator running at approximately 10 kHz in its default configuration. The frequency can be boosted up to 100 kHz by connecting a capacitor to the OSC pin, which increases the output current capability and reduces the size of the required external capacitors. Higher oscillator frequency is beneficial when the load current exceeds a few milliamps and smaller 1 µF capacitors are preferred for PCB space savings.
