ICL7662MTV/B

Overview

The ICL7662MTV/B is a CMOS switched capacitor voltage converter manufactured by Rochester Electronics. It operates within an input voltage range of 4.5 V to 20 V and utilizes a maximum switching frequency of 10 kHz. The device converts positive supply voltages into negative outputs, achieving typical open-circuit efficiency of 99.9% and power efficiency of 96%. It requires only two external non-critical passive components for operation. The component is housed in an 8-lead plastic small outline package (SOIC) with a width of 3.90 mm.

Feature Summary

• Pin-compatible with the ICL7660 series for direct replacement in existing designs
• Eliminates the need for external diodes across the entire operating temperature range
• Provides simple voltage multiplication capabilities using minimal external circuitry

Applications

• Generating localized negative supplies for microprocessors such as the 8080 type
• Providing on-board negative power rails for dynamic RAMs
• Creating inexpensive negative supplies for data acquisition systems
• Supplying up to -20V bias for operational amplifiers

Procurement Notes

Verify the specific suffix 'MTV/B' against official manufacturer documentation to confirm tape-and-reel packaging and lead-free status. Ensure the source document explicitly links this exact part number to the ICL7662 functional specifications before procurement.

Selection Notes

Select this component when a negative voltage rail is required from a single positive source without magnetic components. Verify that the load current requirements fall within the standard output capabilities of the ICL7662 architecture and that the 10 kHz switching frequency is acceptable for the target application's noise sensitivity.

Part Context

This part belongs to the ICL7662 family of CMOS voltage converters originally developed by Intersil and Maxim Integrated. Rochester Electronics provides lifecycle support for these legacy components. The device serves as a charge pump solution for generating inverted polarities in mixed-signal environments.

Replacement Considerations

The ICL7660 is a pin-compatible alternative offering similar functionality. Other CMOS voltage converters may serve as substitutes if pinout compatibility is not required.
