ICL7660CBAZA

Voltage Regulators - DC DC Switching Regulators Overview

The ICL7660CBAZA is a CMOS charge pump voltage converter manufactured by Renesas Electronics Corporation. It operates within an input voltage range of 1.5V to 10V and provides a fixed output configuration supporting positive or negative voltages, specifically -Vin and 2Vin ratios. The device delivers a maximum output current of 45mA with a switching frequency of 10kHz. It is housed in an 8-SOIC surface-mount package measuring 3.90mm in width. The component functions as a DC-DC switch regulator without synchronous rectification and is rated for an operating temperature range of 0°C to 70°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'C' against the manufacturer's latest datasheet to confirm the exact electrical characteristics, such as switching frequency and input voltage limits, as these may vary across the ICL7660 family. Ensure the 8-SOIC package dimensions match the target PCB footprint. Confirm RoHS3 compliance status if required by project specifications.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when an inductor-less solution is required for generating negative or doubled voltage rails from a low-voltage source. Consider the 45mA output current limit and 10kHz switching frequency when designing external capacitor values. Evaluate the thermal performance within the specified commercial temperature range during system integration.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the ICL7660 series of super voltage converters, originally developed by Intersil and now produced by Renesas. The series is designed for applications requiring simple, cost-effective voltage inversion or multiplication. The CBAZA designation indicates a specific variant within the SOIC-8 package lineup, distinct from other variants like the ACBAZA which may feature different switching frequencies.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

The ICL7660ACBAZA is a related variant within the same family, though it typically features a lower switching frequency of 3kHz compared to the 10kHz of the CBAZA. Verify compatibility regarding ripple noise and external component sizing before substitution.
