ICL7660CBA-T

Voltage Regulators - DC DC Switching Regulators Overview

The ICL7660CBA-T is a monolithic CMOS voltage converter IC manufactured by Renesas Electronics Corporation. It functions as a switched-capacitor charge pump with boost and inverting topologies, housed in an SOIC-8 surface-mount package. The device operates within an input voltage range of 1.5 V to 10 V and delivers a maximum output current of 20 mA. It supports a single output configuration with adjustable voltage levels ranging from -12 V to -1.5 V or up to 18.6 V. The internal switching frequency is fixed at 10 kHz, and the component is rated for operation between 0°C and +70°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Monolithic CMOS construction providing significant performance advantages over standard ICL7660 devices
• Integrated boost and inverting charge pump topology for flexible voltage conversion
• Extended operating supply voltage range supporting inputs up to 10 V
• Surface-mount SOIC-8 packaging suitable for automated assembly

Voltage Regulators - DC DC Switching Regulators Applications

• Dynamic RAM board-level negative power supplies
• Centralized microprocessor negative power generation
• Data acquisition systems requiring bipolar power rails

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify RoHS compliance status carefully, as documentation indicates non-compliant variants exist for this part number. Confirm the specific suffix 'T' corresponds to the correct tape-and-reel packaging format required for your manufacturing line. Ensure the selected variant matches the 10 V maximum input rating rather than the extended 12 V rating found in other family members like the SCBAZ series.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact, low-cost solution is needed for generating negative voltages from a positive logic supply. The 20 mA output current limits suitability for high-power applications. Consider the ICL7660SCBAZ-T if an extended 12 V input range or higher 45 mA output current is required. Verify that the fixed 10 kHz switching frequency meets the noise requirements of the target circuit.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the ICL7660S and ICL7660A Super Voltage Converter family. These devices are designed as direct replacements for the industry-standard ICL7660. The family offers improved specifications including lower supply current and extended voltage ranges compared to the original legacy design.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

The ICL7660SCBAZ-T serves as a verified alternative within the same manufacturer's portfolio, offering an extended 12 V input range and 45 mA output capability.
