ICL7660CPA

Voltage Regulators - DC DC Switching Regulators Overview

The ICL7660CPA is a monolithic CMOS voltage converter manufactured by Renesas Electronics Corporation. It operates as a charge pump switching regulator with boost and inverting topology, housed in an 8-pin PDIP package for through-hole mounting. The device accepts an input voltage range of 1.5V to 10V and provides a single adjustable output ranging from -1.5V to -10V. It delivers a maximum output current of 20mA at a nominal switching frequency of 10kHz. The component functions within a commercial temperature range of 0°C to +70°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• CMOS charge pump architecture eliminates the need for external diodes or inductors
• Integrated logic prevents latch-up by monitoring negative voltage levels
• Supports both inverting and voltage doubling configurations using minimal external components

Voltage Regulators - DC DC Switching Regulators Applications

• Providing negative power supplies for dynamic RAM circuits
• Generating negative bias for centralized microprocessor systems such as 8080-type architectures
• Supplying negative rails for data acquisition systems

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify component status prior to procurement as the ICL7660CPA is listed as obsolete by the manufacturer. Confirm availability through authorized distributors or secondary markets. Ensure that the PDIP-8 package and through-hole installation requirements align with the target PCB design. Validate RoHS compliance status against specific revision requirements, as legacy parts may vary in environmental certification.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a simple, low-cost solution for generating negative voltages from a positive source is required. It is suitable for applications where moderate output current up to 20mA is sufficient. Consider the PDIP-8 package constraints for board layout. For higher current demands or industrial temperature ranges, evaluate variants such as the ICL7660ACPAZ or ICL7660SIBAZ instead.

Voltage Regulators - DC DC Switching Regulators Part Context

The ICL7660CPA belongs to the Intersil/Renesas ICL7660 family of super voltage converters. This series is designed for efficient positive-to-negative voltage conversion without magnetic components. The CPA variant specifically denotes the commercial grade version with through-hole packaging, distinguishing it from surface-mount or industrial temperature rated alternatives within the same product line.
