ICL7660SCPAZ

Voltage Regulators - DC DC Switching Regulators Overview

The ICL7660SCPAZ is a charge pump switching regulator IC manufactured by Renesas Electronics. It operates within an input voltage range of 1.5V to 12V and provides a single output configured as positive or negative fixed -Vin or 2Vin. The device delivers a maximum output current of 45mA with a typical switching frequency between 10kHz and 35kHz. It is housed in an 8-DIP package (0.300 inch, 7.62mm pitch) and supports an operating temperature range from -40°C to 85°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Utilizes charge pump topology for DC-DC conversion without requiring inductors
• Provides flexible output configuration supporting both positive and negative voltage generation
• Operates across a wide input voltage range suitable for various low-power applications

Voltage Regulators - DC DC Switching Regulators Applications

• Dynamic RAM board-level negative power supply generation
• Negative power supply for centralized microprocessor systems

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'SCPAZ' against the manufacturer's latest documentation to confirm pinout compatibility and RoHS status. Ensure the DIP-8 package dimensions match the target PCB footprint. Confirm that the 45mA output current meets the load requirements, as this is a fixed specification for this variant. Check for any obsolescence notices or alternative package recommendations from Renesas.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when an inductor-free solution is required for generating inverted or doubled voltages from a single supply. The 8-DIP package is suitable for prototyping or through-hole designs where surface-mount options are not feasible. Consider the 45mA current limit and switching frequency characteristics to ensure adequate filtering capacitors are used for stable operation under the intended load conditions.

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 needing simple voltage inversion or multiplication. The SCPAZ designation indicates a specific package and environmental compliance variant within the broader family of charge pump regulators.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include the ICL7660SIPAZ and ICL7660ACPA, though package differences exist. Verify functional equivalence regarding output current and switching frequency before replacing. Cross-reference with other 8-pin charge pump regulators if the DIP package is no longer available.
