ICL7660CBAZA-T

Voltage Regulators - DC DC Switching Regulators Overview

The ICL7660CBAZA-T is a monolithic CMOS voltage converter IC manufactured by Renesas Electronics Corporation. It functions as an inverting charge pump switching regulator designed to convert positive supply voltages into negative outputs. The device operates within an input voltage range of 1.5V to 12V and provides a maximum output current of 20mA. It utilizes a standard 8-SOIC surface-mount package with a pitch of 1.3mm. The component supports a typical switching frequency of 10kHz and is rated for commercial temperature operation between 0°C and +70°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Monolithic CMOS construction ensures low power consumption and high efficiency compared to similar devices.
• Integrated frequency boost capability allows for lower output impedance when using smaller external capacitors.
• Direct replacement for the industry-standard ICL7660 with extended operating voltage support up to 12V.
• Includes improved silicon latch-up protection for enhanced reliability across operating conditions.

Voltage Regulators - DC DC Switching Regulators Applications

• Generating negative power supplies for data acquisition systems and instrumentation
• RS-232 interface power supply generation
• Supply splitting to create complementary positive and negative rails from a single source

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify that the specific suffix 'T' confirms tape-and-reel packaging rather than tube configuration, as this affects handling and assembly equipment requirements. Confirm the 'C' grade designation aligns with the required commercial temperature range of 0°C to +70°C for your specific application environment. Ensure compatibility with the 8-SOIC footprint dimensions during PCB layout finalization.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact, inverting DC-DC solution is needed without inductors. It is suitable for applications requiring moderate current levels around 20mA. Consider the ICL7660A series if industrial temperature ratings or higher output currents are necessary. Evaluate external capacitor values against the desired switching frequency and output ripple specifications.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the ICL7660 family of super voltage converters, originally introduced by Intersil and now produced by Renesas. The family represents a standard solution for simple voltage inversion tasks in mixed-signal circuits. The CBAZA variant specifically denotes the commercial temperature grade housed in an SOIC-8 package, distinguishing it from wider temperature or leaded-package alternatives.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

The ICL7660AIBAZA-T serves as a verified substitute offering extended voltage ranges and industrial temperature capabilities. Other compatible options include the ICL7660SCBAZ for broader thermal performance. Verify pinout compatibility and electrical parameters before substituting to ensure circuit stability.
