ICL7660SIPA

Voltage Regulators - DC DC Switching Regulators Overview

The ICL7660SIPA is a CMOS switched-capacitor voltage converter manufactured by Harris Corporation. It functions as a charge pump capable of generating negative voltages from positive inputs or multiplying input voltages. The device operates with an input voltage range of 1.5V to 12V and provides a maximum output current of 45mA. It utilizes an internal oscillator with a switching frequency of approximately 10kHz. The component is housed in an 8-pin PDIP package, suitable for through-hole mounting applications requiring efficient DC-DC conversion without inductors.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'IPA' against manufacturer documentation to confirm pinout compatibility and package dimensions. Ensure the source document explicitly lists Harris Corporation as the original manufacturer for this part number variant. Cross-reference electrical specifications with standard ICL7660 datasheets to confirm operational parameters match your system requirements before procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when designing circuits that require simple, inductor-free voltage inversion or multiplication. It is suitable for low-current applications up to 45mA where cost and board space are constraints. Consider the PDIP package if through-hole assembly is required. Verify that the load current does not exceed the rated limit to maintain regulation stability.

Voltage Regulators - DC DC Switching Regulators Part Context

The ICL7660 series represents a family of classic switched-capacitor converters widely used in analog signal processing. Harris Corporation was a primary developer of this architecture before its acquisition by Intersil and subsequently Renesas. This specific model belongs to the standard ICL7660 line, distinguished primarily by its packaging and manufacturing origin.
