ICL7660EPA+

Voltage Regulators - DC DC Switching Regulators Overview

The ICL7660EPA+ is a switched-capacitor voltage converter manufactured by Analog Devices Inc./Maxim Integrated. It operates within 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 supports negative output voltages from -10 V to -1.5 V and positive outputs from 3 V to 20 V. The component is housed in an 8-PDIP package and functions reliably across an operating temperature range of -40°C to +85°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Capable of generating both positive and negative voltage outputs from a single supply source
• Operates without the need for external inductors, utilizing a switched-capacitor architecture
• Includes a shutdown feature to minimize power consumption during inactive periods

Voltage Regulators - DC DC Switching Regulators Applications

• Bipolar power supply generation for operational amplifiers
• RS-232 transceiver interface circuits
• Data acquisition systems requiring dual polarity rails

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify that the specific suffix 'EPA+' corresponds to the commercial grade variant with the specified industrial temperature range (-40°C to +85°C) and PDIP-8 packaging. Confirm RoHS compliance status as documentation indicates potential variations. Ensure the obsolete status of the base ICL7660ESA does not preclude the availability of the '+' suffix version through authorized channels.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when designing circuits that require isolated positive and negative rails from a single low-voltage source without magnetic components. It is suitable for applications where moderate current loads up to 20 mA are sufficient. Consider the 10 kHz switching frequency for EMI sensitivity and ensure adequate decoupling capacitors are placed near the input and output pins to maintain stability.
