Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific die variant and packaging requirements when sourcing this component. As a die-level product, it requires specialized mounting and assembly processes compared to standard packaged ICs. Confirm compatibility with your PCB design and thermal management strategy before procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when inductor-less voltage conversion is required in a compact form factor. Consider the 20mA output current limit and 10kHz switching frequency for noise-sensitive applications. Ensure the input voltage range aligns with the system requirements for stable ratiometric operation.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the ICL7660 family of switched-capacitor voltage converters. It is distinct from packaged versions like the ICL7660ESA+ by its die format, which allows for direct integration into custom substrates or hybrid circuits. The family is known for low power consumption and simple external component requirements.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct replacements include other ICL7660 variants such as ICL7660ESA+ or ICL7660CUA+, though these are packaged devices. For die-level equivalents, consult manufacturer documentation for compatible bare die options within the same series.
