ICL7660CBAZ

Voltage Regulators - DC DC Switching Regulators Overview

The ICL7660CBAZ is a CMOS voltage converter IC manufactured by Renesas Electronics Corporation, belonging to the ICL7660 series. It functions as a charge pump switching regulator capable of generating positive or negative fixed output voltages relative to the input. The device operates with an input voltage range from 1.5V to 10V and provides a maximum output current of 20mA. It utilizes a 10kHz switching frequency and is housed in an 8-SOIC surface-mount package with a width of 3.90mm. The component supports boost and inverting topologies and is rated for operation between 0°C and +70°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'C' against the manufacturer's latest datasheet to confirm pinout compatibility and electrical tolerances. Ensure the SOIC-8 package dimensions match the target PCB footprint. Confirm RoHS compliance status if required by assembly specifications. Check for any recent Product Change Notifications regarding labeling or manufacturing site updates.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a simple, inductor-less solution is required for voltage inversion or boosting within low-current applications. The 20mA output limit suits light loads such as memory biasing or sensor interfaces. Consider the 10kHz switching frequency for noise-sensitive designs where lower frequencies are acceptable. Verify that the 1.5V minimum input voltage aligns with the system power source.
