ICL7660CBAZ-T

Voltage Regulators - DC DC Switching Regulators Overview

The ICL7660CBAZ-T is a monolithic CMOS charge pump voltage converter manufactured by Renesas Electronics Corporation. It operates within an input voltage range of 1.5V to 10V and provides a single fixed output configuration capable of generating positive or negative voltages relative to the input, specifically -Vin or 2Vin. The device delivers a maximum output current of 45mA with a typical switching frequency of 10kHz. It is housed in an 8-SOIC surface-mount package with a width of 3.90mm and functions reliably across a commercial temperature range of 0°C to 70°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• CMOS charge pump topology for inductorless DC-DC conversion
• Capable of generating inverted (-Vin) or doubled (2Vin) output voltages
• Integrated frequency boost capability for reduced output impedance

Voltage Regulators - DC DC Switching Regulators Applications

• Converting +5V logic power supplies to ±5V dual rails
• General-purpose voltage inversion for analog circuits
• Step-up voltage conversion for low-power digital systems

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging rather than tube. Confirm the manufacturer designation as Renesas Electronics Corporation, noting historical Intersil origins. Ensure the operating temperature range matches the commercial grade (0°C to 70°C) required for the application environment. Cross-reference the 8-SOIC package dimensions against PCB footprint requirements.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when an inductorless solution is required for voltage inversion or doubling within a 1.5V to 10V input window. It is suitable for applications prioritizing low component count over high efficiency at heavy loads. Consider the 45mA output limit and 10kHz switching frequency when designing external capacitor values for ripple and impedance optimization.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the ICL7660 family of super voltage converters, originally introduced by Intersil and now produced by Renesas. It serves as a direct replacement for legacy industry-standard ICL7660 devices while offering improved performance characteristics such as lower supply current and extended voltage ranges in related variants like the ICL7660A/S.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct replacements include the ICL7660SCBAZ-T and ICL7660AIBAZA-T. Verify compatibility regarding input voltage limits, as the A and S variants support up to 12V compared to the C variant's 10V limit.
