ICL7660CPA

Voltage Regulators - DC DC Switching Regulators Overview

The ICL7660CPA is a monolithic CMOS switched-capacitor voltage converter manufactured by Harris Corporation. It operates within an input voltage range of 1.5V to 10V and provides a fixed single output. The device supports boost and inverting topologies with a typical switching frequency of 10 kHz. It delivers up to 45 mA of output current and functions reliably without external diodes across the full temperature range.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Monolithic CMOS construction for high efficiency
• Integrated oscillator eliminates need for external timing components
• Diode-free operation ensures reliable performance at higher voltages

Voltage Regulators - DC DC Switching Regulators Applications

• Generating negative supply rails from positive logic supplies
• Data-acquisition systems requiring dual polarity power
• Portable instruments needing efficient voltage inversion

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify manufacturer origin as Harris Corporation or successor entities like Intersil/Renesas due to legacy status. Confirm package integrity for SOIC-8 variant. Check RoHS compliance documentation specifically for this part number, as older Harris batches may differ from modern equivalents. Ensure datasheet revision matches required electrical tolerances.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a simple, low-cost solution for voltage inversion or doubling is required. It is suitable for applications where moderate output current around 20-45 mA is sufficient. Consider thermal management if operating near maximum input voltage limits. Verify that the 10 kHz switching frequency does not interfere with sensitive analog circuits in the design.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the ICL7660 family of charge pump ICs. It serves as a direct replacement for industry-standard voltage converters. The CPA suffix typically denotes a plastic DIP or SOIC package variant depending on the specific manufacturing run and distributor listing conventions for Harris/Intersil products.
