ICL7660SIBA

Voltage Regulators - DC DC Switching Regulators Overview

The ICL7660SIBA is a monolithic CMOS Super Voltage Converter manufactured by Harris Corporation. It functions as an inverting charge pump DC-DC converter, generating a negative output voltage from a positive input supply within the range of 1.5V to 12V. The device provides a maximum output current of 45mA and operates with a nominal switching frequency of 10kHz at 5V input. It utilizes an internal RC oscillator and four power MOS switches to achieve voltage inversion without external inductors.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the manufacturer designation on the component marking, as Renesas Electronics acquired Intersil assets which include this product line. Confirm the suffix 'IBA' corresponds to the specific package and temperature grade required for your application. Ensure compliance with RoHS directives if applicable to your manufacturing standards. Cross-reference datasheet revisions to confirm pinout consistency with legacy designs.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when an inverting topology is required for low-to-medium current loads. It is suitable for applications where inductor-based converters are undesirable due to size or cost constraints. Consider the 10kHz switching frequency for noise-sensitive designs, as lower frequencies may require larger external capacitors. Evaluate the 45mA output limit against peak load requirements to ensure stable regulation under all operating conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

The ICL7660 series represents a family of super voltage converters designed to replace older discrete solutions. The ICL7660SIBA variant specifically denotes the commercial/industrial grade version in an SOIC-8 package. It belongs to the broader class of switched-capacitor voltage converters, offering a compact alternative to magnetic-based DC-DC converters for small form-factor electronics.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

The ICL7660SCBA is a documented direct replacement offering similar electrical characteristics. Verify that the substitute part meets the specific temperature range and package tolerance requirements of the original design. Check for any minor differences in external capacitor recommendations between the Harris and subsequent manufacturer datasheets.
