ICL3244CB

Overview

The ICL3244CB is a CMOS switching regulator manufactured by Harris Corporation. It operates with an input voltage range from 1.15 V to 4 V, typically centered around 1.2 V. The device provides a nominal output voltage of 5 V and supports a maximum output current of 1.6 A. It functions at a maximum switching frequency of 24 kHz. The component is housed in a 14-lead Plastic Dual In-line Small Outline (SOP) package, specifically JESD-30 code R-PDSO-G14. It is designed for operation within a temperature range up to 70 °C.

Feature Summary

• CMOS technology implementation for power efficiency
• Integrated switching regulator functionality
• Low voltage input capability

Applications

• Portable electronic devices requiring low voltage regulation
• Battery-powered systems utilizing CMOS logic
• General purpose DC-DC conversion circuits

Procurement Notes

Verify the manufacturer designation as Harris Corporation on the component marking. Confirm the package type is SOP-14 and check for RoHS compliance status, as the source data indicates non-compliance. Ensure the operating temperature rating meets the specific application requirements of 70 °C maximum.

Selection Notes

Select this component when a low-cost, low-frequency switching regulator is required for inputs between 1.15 V and 4 V. The 1.6 A output current capacity suits moderate load applications. Consider the 24 kHz switching frequency for noise-sensitive designs where lower EMI is beneficial compared to higher frequency alternatives.

Part Context

The ICL3244CB belongs to the ICL series of integrated circuits produced by Harris Corporation. This series includes various power management components. The CB suffix typically denotes the commercial temperature grade and plastic packaging variant. Harris Corporation was a significant producer of semiconductor products before its acquisition by Raytheon.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-reference with other CMOS switching regulators offering similar 1.6 A output and 5 V nominal voltage if direct replacement is necessary.
