ICL7660ACBA-T

Voltage Regulators - DC DC Switching Regulators Overview

The ICL7660ACBA-T is a monolithic CMOS voltage converter IC designed for inverting and step-up applications. It operates with an input voltage range of 1.5V to 12V, providing a negative output voltage ranging from -1.5V to -12V. The device supports a maximum output current of 45mA and functions at a switching frequency of 10kHz. It is housed in an 8-pin SOIC surface-mount package and is rated for commercial operating temperatures between 0°C and 70°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Monolithic CMOS construction ensures low supply current consumption

• Extended operating supply voltage range up to 12V compared to standard models
• Guaranteed performance across the entire commercial temperature range

Voltage Regulators - DC DC Switching Regulators Applications

• Simple conversion of +5V logic supplies to ±5V dual rails
• Negative power supplies for data acquisition systems and instrumentation
• RS232 interface power supply generation
• Voltage multiplication circuits requiring complementary outputs

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify that the suffix 'T' confirms tape-and-reel packaging rather than tube distribution. Confirm the 'C' designation aligns with the required commercial temperature range (0°C to 70°C) for your specific application environment. Ensure the manufacturer is identified as Intersil or its successor Renesas Electronics to guarantee component authenticity and datasheet consistency.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when an inverting charge pump topology is required for low-power signal conditioning or RS232 interfaces. It serves as a direct replacement for the industry-standard ICL7660 but offers improved efficiency and extended voltage tolerance. Consider the 45mA output limit and 10kHz switching frequency when designing external capacitor networks for ripple reduction.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the ICL7660S/A family of super voltage converters, which are enhanced versions of the original ICL7660. The family provides significant performance advantages over older similar devices, including lower quiescent current and higher maximum input voltage capabilities. These ICs are widely used in industrial and consumer electronics for generating negative voltages from single positive supplies.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

The ICL7660SCBAZ-T is a verified substitute within the same product family. Both parts share identical electrical characteristics and pinouts, differing primarily in manufacturing lot details or minor packaging variations. Verify that the substitute maintains the same SOIC-8 footprint and thermal ratings.
