ICL7660ESA

Voltage Regulators - DC DC Switching Regulators Overview

The ICL7660ESA is a switched-capacitor voltage converter manufactured by Analog Devices Inc./Maxim Integrated. It operates as a charge pump DC-DC switching regulator capable of generating positive or negative fixed outputs from a single input source. The device accepts an input voltage range of 1.5V to 10V and provides a maximum output current of 20mA with one output channel. It functions at a switching frequency of 10kHz and is housed in an 8-SOIC surface-mount package. The component supports an operating temperature range of -40°C to +85°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Capable of converting input voltages to either positive or negative fixed output levels using a charge pump topology
• Operates without external inductors, utilizing only capacitors for energy storage and voltage conversion
• Includes shutdown functionality to minimize power consumption during inactive periods

Voltage Regulators - DC DC Switching Regulators Applications

• Applications requiring dual polarity power supplies derived from a single positive voltage source
• Low-power analog circuits needing negative bias voltages
• Battery-powered systems requiring efficient voltage inversion without inductive components

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix designation when sourcing replacements, as it indicates environmental compliance status. Confirm that the obsolete status does not impact long-term supply chain stability for existing designs. Ensure compatibility with RoHS directives if required by the target application regulations. Cross-reference pinouts carefully against datasheets to prevent integration errors.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component for designs requiring simple voltage inversion or boosting without the complexity of inductor-based converters. Consider the 20mA output limit and 10kHz switching frequency when evaluating ripple and load requirements. Verify thermal performance within the specified industrial temperature range. Check for available direct substitutes if new production is necessary due to end-of-life status.
