UCD9244ARGCR

Power Management - Specialized Overview

The UCD9244ARGCR is a digital PWM system controller from Texas Instruments, designed for high-performance voltage regulator applications. It supports 4-bit, 6-bit, or 8-bit VID (Voltage ID) inputs for flexible voltage configuration. The device operates within an input voltage range of 3 V to 3.6 V and functions reliably across a temperature range of -40°C to +125°C. Packaged in a VQFN-64 format, it integrates advanced control features suitable for complex power management requirements.

Power Management - Specialized Feature Summary

• Supports multiple VID code resolutions including 4-bit, 6-bit, and 8-bit configurations for precise voltage setting.

Power Management - Specialized Applications

• High-density server power supplies
• Graphics processing unit (GPU) voltage regulation modules
• Central processing unit (CPU) VRM designs

Power Management - Specialized Procurement Notes

Verify the specific suffix 'RGCT' versus 'ARGCR' when ordering, as package variations may exist. Confirm RoHS compliance status through official datasheets. Ensure ESD handling protocols are followed due to moisture sensitivity classification. Cross-reference with the latest TI documentation for any pinout or functional revisions.

Power Management - Specialized Selection Notes

Select this component for applications requiring digital control flexibility and multi-phase synchronization. Evaluate compatibility with external MOSFET drivers if not integrated. Consider the thermal performance of the VQFN-64 package for your specific PCB layout constraints. Verify that the required VID resolution matches your system's voltage adjustment needs.

Power Management - Specialized Part Context

This part belongs to the UCD92xx series of Fusion Digital Power controllers by Texas Instruments. These controllers utilize an ARM7 core for digital signal processing, enabling advanced loop compensation and protection features. The series is targeted at telecom, data storage, and industrial applications demanding high efficiency and dynamic response.

Power Management - Specialized Replacement Considerations

Check for UCD9244 variants with different suffixes for package changes. Review UCD9222 as a related controller in the same family. Ensure substitute parts maintain compatible VID interfaces and operating voltage ranges.
