UCC39002DR

Product Overview

The Texas Instruments UCC39002DR is a load share controller housed in an 8-SOIC surface-mount package. It is a specialized power-management IC intended for power-management designs that require load-current sharing. The device operates from a supply voltage range of 4.375V to 14.25V and draws 2.5mA of supply current. Its specified operating temperature range is 0°C to 70°C. The 8-SOIC case measures 0.154 inches, or 3.90mm, in width, for board layouts using surface-mount assembly.

Key Features

• Load share controller function for power-management circuits
• 8-SOIC surface-mount package with 0.154 inch, 3.90mm width
• Supply voltage range of 4.375V to 14.25V
• Supply current of 2.5mA
• Operating temperature range of 0°C to 70°C
• Manufacturer part number UCC39002DR from Texas Instruments

Applications

• Power-supply subsystems requiring load-current sharing between outputs
• Embedded systems with several power outputs that need load-current balancing
• Power distribution boards using controller-based current sharing among supply stages

Design & Procurement Notes

When using the UCC39002DR, verify that the controller supply voltage remains within 4.375V to 14.25V and that the 2.5mA supply current is included in the power budget. The specified operating temperature range is 0°C to 70°C, so thermal design should consider the ambient environment around the 8-SOIC package. Because the device uses an 8-SOIC surface-mount case, PCB land patterns, reflow profiles, and mechanical clearances should match the 0.154 inch, 3.90mm package width. Procurement should reference the exact Texas Instruments part number UCC39002DR and the 8-SOIC package to ensure the intended mounting style and footprint are obtained.
