ICL7660SCBA-T

Voltage Regulators - DC DC Switching Regulators Overview

The ICL7660SCBA-T is a CMOS voltage converter manufactured by Renesas Electronics, designed for efficient power management in compact applications. It operates within an input voltage range of 1.5 V to 10 V and provides a single adjustable output ranging from -12 V to -1.5 V. The device delivers a maximum output current of 20 mA with a nominal switching frequency of 10 kHz. Encased in an SOIC-8 surface-mount package, it functions as a charge pump regulator suitable for industrial temperature ranges from 0°C to +70°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• CMOS technology enables low quiescent current consumption for energy-efficient operation
• Requires only two external non-critical passive components for basic functionality
• Integrated logic prevents latch-up by monitoring negative voltage levels
• Supports both inverting and voltage multiplier topologies without external diodes

Voltage Regulators - DC DC Switching Regulators Applications

• On-board negative power supplies for dynamic RAM
• Negative power sources for centralized microprocessors
• Data acquisition systems requiring dual polarity rails

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging configuration. Confirm RoHS compliance status as some listings indicate non-compliance while others suggest lead-free variants exist. Ensure the supplier source aligns with Renesas Electronics or authorized Intersil distribution channels to guarantee authenticity and traceability of the component batch.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a simple, cost-effective solution for generating negative voltages from a positive supply is required. It is ideal for designs where space constraints preclude the use of inductors. Consider the 20 mA output limit and 10 kHz switching frequency against system noise and load requirements before finalizing the design.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the ICL7660 series of CMOS voltage converters originally developed by Intersil and now managed by Renesas Electronics. The series is known for its simplicity and reliability in converting positive logic power supplies into complementary negative voltages, widely used in legacy and modern mixed-signal circuits.
