ICL7660SCPA

Voltage Regulators - DC DC Switching Regulators Overview

The ICL7660SCPA is a monolithic CMOS voltage converter manufactured by Renesas Electronics Corporation. It operates as a charge pump switching regulator with an inverting and boost topology, housed in an 8-PDIP package for through-hole mounting. The device supports an input voltage range of 1.5V to 10V, generating an adjustable output voltage from -1.5V to -10V. It provides a maximum output current of 20mA at a nominal switching frequency of 10kHz. The component functions within a temperature range of 0°C to +70°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Data acquisition systems requiring dual polarity rails

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'CPA' corresponds to the PDIP-8 through-hole package variant. Confirm that the standard ICL7660 specifications apply, specifically the 10V maximum input limit and 20mA output current rating. Check manufacturer lifecycle status as some variants may be discontinued or superseded by the ICL7660A series. Ensure RoHS compliance requirements are met if applicable to the specific production batch.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a simple, low-cost solution for generating negative voltages from a positive logic supply is required. It is suitable for applications where moderate output current up to 20mA is sufficient. Consider the ICL7660A series if input voltages exceed 10V or if an extended industrial temperature range is necessary. This part is ideal for designs prioritizing minimal external component count and ease of integration.
