ICL7660ACPA

Voltage Regulators - DC DC Switching Regulators Overview

The ICL7660ACPA is a monolithic CMOS voltage converter manufactured by Harris Corporation, functioning as a switched-capacitor charge pump. It operates within an input voltage range of 1.5 V to 12 V and delivers a maximum output current of 45 mA. The device utilizes a 3 kHz switching frequency for inverting or boosting applications. It is housed in an 8-pin DIP package with a dual inline form factor. The component supports fixed positive or negative output configurations and is designed for commercial temperature ranges from 0°C to 70°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Monolithic CMOS construction providing high efficiency with minimal external components
• Capable of converting positive supply voltages to complementary negative outputs
• Integrated charge pump topology eliminates the need for inductors
• Low standby current consumption suitable for battery-powered systems

Voltage Regulators - DC DC Switching Regulators Applications

• Generating negative supply rails for operational amplifiers
• RS-232 communication interface power supplies
• Data acquisition system instrumentation power
• Portable handheld meter power management

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the manufacturer designation carefully, as the ICL7660 family was originally developed by Intersil and later acquired by Renesas Electronics. Confirm that the specific batch corresponds to Harris Corporation production if legacy sourcing is required. Ensure the package matches the 8-DIP specification and validate RoHS compliance status against current regulatory requirements for the specific manufacturing date code.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a simple, low-cost solution is needed for small signal polarity inversion without magnetic components. It is appropriate for applications requiring moderate current levels up to 45 mA. Consider the 3 kHz switching frequency limitations regarding output ripple and noise sensitivity compared to higher-frequency alternatives. Ensure the PCB layout accommodates the through-hole DIP footprint constraints.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the ICL7660 series of super voltage converters, which are widely recognized industry standards for charge-pump applications. The ACPA suffix denotes the specific package variant and temperature rating. These devices are frequently used as direct replacements for older Maxim or Intersil designs in established electronic architectures requiring stable voltage conversion.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

The TC7660 and MAX1044 are documented as electrically compatible and pin-compatible alternatives. Verify that substitute parts maintain the same 45 mA output current capability and 3 kHz switching frequency characteristics to ensure circuit performance parity.
