UCC39002DGKR

Power Management - Specialized Overview

The UCC39002DGKR is an advanced load-share controller from Texas Instruments, designed for parallel power supply systems. It operates within a supply voltage range of 4.375V to 14.25V and draws a typical supply current of 2.5mA. The device features a VSSOP-8 package with a maximum output voltage of 1.005V and supports an output current of 1.5mA. It functions across a temperature range of 0°C to +70°C.

Power Management - Specialized Feature Summary

• Provides high-accuracy current sharing capability with less than 1% error at full load using a low-offset current-sense amplifier.
• Supports both high-side and low-side (GND-referenced) current sensing configurations for flexible system design.
• Utilizes a leader/follower architecture to manage parallel modules without requiring external master control logic.

Power Management - Specialized Applications

• N+1 redundant server power systems
• Distributed power architectures in telecom equipment
• High-current workstation power supplies

Power Management - Specialized Procurement Notes

Verify the specific suffix DGKR confirms the VSSOP-8 tape-and-reel packaging variant. Confirm RoHS compliance status as per the latest manufacturer documentation. Ensure the component meets the required operating temperature range for the target application environment before finalizing procurement.

Power Management - Specialized Selection Notes

Select this component when designing systems requiring precise load balancing between multiple DC-to-DC modules. It is suitable for applications needing Intel SSI load-share specification compliance. Consider the VSSOP-8 package size constraints and the need for external current-sense resistors during the schematic design phase.
