ICL7660CSA+

Voltage Regulators - DC DC Switching Regulators Overview

The ICL7660CSA+ is a switched-capacitor voltage converter manufactured by Analog Devices Inc./Maxim Integrated. It operates with an input voltage range of 1.5 V to 10 V and provides a single output capable of delivering up to 20 mA. The device utilizes a boost or inverting topology with a fixed switching frequency of 10 kHz. It is housed in an SOIC-8 surface-mount package and is rated for operation within a temperature range of 0°C to +70°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Provides inverting and boost voltage conversion capabilities without requiring inductors
• Operates at a fixed 10 kHz switching frequency to minimize external component size
• Features low quiescent current consumption for efficient power management

Voltage Regulators - DC DC Switching Regulators Applications

• Data acquisition systems requiring negative supply rails
• Portable instrumentation and handheld devices
• Op-amp biasing circuits needing dual polarity supplies

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the commercial grade temperature rating (0°C to +70°C) against application requirements, as industrial variants exist. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the SOIC-8 footprint matches the design layout. Check for end-of-life notices or obsolescence warnings from the manufacturer before finalizing procurement plans.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when inductor-free DC-DC conversion is required for low-power applications. Compare against the ICL7660ESA+ if an extended industrial temperature range (-40°C to +85°C) is necessary. Consider the TC7660EOA for cost-sensitive designs where similar performance specifications are acceptable. Evaluate output current demands to ensure they remain within the 20 mA limit.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the ICL7660 family of CMOS voltage converters designed for small form-factor power solutions. It serves as a direct replacement for older Intersil and Renesas versions of the same functional architecture. The device eliminates the need for bulky magnetic components, making it suitable for space-constrained portable electronics and battery-operated systems.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include ICL7660ESA+ and ICL7660ISA+. Alternative equivalents are LMC7660IM/NOPB and TC7660EOA.
