ICL7660SCPA

Voltage Regulators - DC DC Switching Regulators Overview

The ICL7660SCPA is a monolithic CMOS super voltage converter manufactured by Intersil. It functions as a charge pump to convert positive input voltages into negative outputs or multiply voltages. The device operates with an input voltage range of 1.5V to 12V and provides a single output capable of delivering up to 45mA. It utilizes a switching frequency of 10kHz, which can be boosted for lower output impedance. The component is housed in an 8-pin PDIP package and is designed for through-hole mounting.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Converts positive logic supplies to complementary negative supplies without external diodes
• Incorporates a dedicated boost pin to enable higher switching frequencies with smaller capacitors
• Features improved SCR latchup protection to ensure stable operation across temperature ranges
• Requires only two external non-critical passive components for basic configuration

Voltage Regulators - DC DC Switching Regulators Applications

• Generating negative power supplies for data acquisition systems
• Providing split supplies (±VS) for instrumentation circuits
• Powering RS-232 communication interfaces
• Supplying negative rails for operational amplifiers

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'CPA' indicates the PDIP-8 through-hole package variant. Confirm RoHS compliance status as older manufacturing runs may differ from current specifications. Check for end-of-life notices or obsolescence warnings from Renesas/Intersil before finalizing procurement plans.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a simple, low-cost solution is required to invert polarity or generate negative voltages from a single positive rail. It is suitable for applications where moderate output current is sufficient and board space allows for through-hole mounting. Consider the ICL7660SCBAZ if surface-mount technology is preferred.
