ICL7660SMTV

Voltage Regulators - DC DC Switching Regulators Overview

The ICL7660SMTV is a monolithic CMOS voltage converter manufactured by Rochester Electronics, LLC. It functions as a switched capacitor charge pump capable of converting positive supply voltages to negative outputs or boosting input levels. The device operates within an input voltage range of 1.5 V to 12 V and supports a maximum switching frequency of 35 kHz. It is housed in an 8-lead SOIC surface-mount package with a pitch of 1.3 mm. The component is rated for industrial temperature operation from -40°C to +85°C and features a maximum output current capability of 45 mA.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• CMOS technology ensures low supply current consumption during operation.
• Integrated frequency boost pin allows for reduced output impedance when using smaller external capacitors.
• Direct replacement compatibility with industry standard ICL7660 devices.
• Guaranteed critical parameters across the full industrial temperature range.

Voltage Regulators - DC DC Switching Regulators Applications

• Generating negative power supplies for dynamic RAM circuits
• Providing bias voltages for operational amplifiers requiring dual supplies
• Creating inverted voltage rails for microprocessor systems

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify that the specific lot corresponds to the ICL7660S variant rather than the base ICL7660, as the S version offers extended voltage ranges and lower current. Confirm the suffix indicates the tape-and-reel packaging format if automated assembly is required. Ensure the procurement source provides traceability documentation consistent with Rochester Electronics standards for refurbished or surplus components.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when an inductorless solution is preferred for compact board space. The ICL7660SMTV is suitable for applications requiring moderate current loads up to 45 mA. Consider the external capacitor requirements carefully, as the frequency boost feature optimizes performance with smaller capacitance values compared to legacy equivalents.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the ICL7660 family of super voltage converters originally developed by Intersil. Rochester Electronics licenses and distributes these parts, often providing updated versions like the 'S' variant which improves upon original specifications. The family is widely recognized for simple, cost-effective voltage inversion without magnetic components.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

The ICL7660SCBA and ICL7660AIBA are documented functional equivalents within the same product family. Verify pinout compatibility and thermal characteristics before substituting, as package dimensions may vary between SOIC and DIP formats.
