What are the key features of TL7660CPE4?

Switched-capacitor voltage inverter converts positive supply to equivalent negative voltage
Wide input voltage range from 1.5V to 10V with negative output tracking the input
Simple external circuit requiring only two capacitors for full operation
8-pin DIP package ideal for through-hole prototyping and low-volume production
Low quiescent current consumption suitable for battery-powered applications

What is TL7660CPE4 used for?

The TL7660CPE4 is commonly used to generate a negative supply rail from a single positive supply in analog circuits, operational amplifier bias networks, and RS-232 transceiver charge pumps. It is ideal for battery-powered instrumentation, portable test equipment, and analog front-end circuits where a negative supply must be derived without a transformer or secondary winding.

Frequently Asked Questions

What does the TL7660CPE4 do and what is its input voltage range?

The TL7660CPE4 is a switched-capacitor voltage converter that generates a negative output voltage equal in magnitude to the positive input voltage. It operates from an input voltage range of 1.5V minimum to 10V maximum, with a nominal design point of 3V. The output voltage tracks the input, making it a simple negative rail generator.

What external components does the TL7660CPE4 require?

The TL7660CPE4 requires only two external capacitors for operation: a charge reservoir capacitor (typically 10µF) connected between the CAP+ and CAP- pins, and an output filter capacitor (typically 10µF) connected between the output and ground. No inductors or transformers are needed, simplifying PCB layout significantly.

What package is the TL7660CPE4 available in and is it RoHS compliant?

The TL7660CPE4 is available in an 8-pin dual in-line package (PDIP) with JESD-30 code R-PDIP-T8. The E4 suffix indicates it is lead-free and RoHS compliant per JESD-609 code e4. This through-hole package is well suited for prototyping and applications where socketed ICs are preferred.

Can the TL7660CPE4 be used to double the supply voltage instead of inverting it?

Yes, by connecting the TL7660CPE4 with the OS (oscillator select) pin and using an appropriate external configuration, the device can be used in a voltage-doubling mode to generate an output approximately twice the input voltage. This flexibility makes it useful both for voltage inversion and voltage multiplication in power conversion applications.
