UC2907N

UC2907N Description

The UC2907N from Texas Instruments is a specialized Load Share Controller IC designed for precise current sharing in parallel power supply systems. Housed in a 16-pin DIP package, it operates over a wide 4.5V to 35V supply range with a modest 6mA supply current, making it suitable for high-efficiency power management applications. This device ensures balanced current distribution across multiple power modules, enhancing system reliability and performance. With ROHS3 compliance and REACH unaffected status, it meets stringent environmental standards. Its last-time-buy status indicates end-of-life availability, urging designers to secure stock for legacy or long-term projects.

UC2907N Features

• Wide Supply Range (4.5V–35V): Supports diverse power architectures, from low-voltage to industrial-grade systems.
• Low Quiescent Current (6mA): Minimizes power loss, ideal for energy-sensitive applications.
• Precision Load Sharing: Ensures equitable current distribution, preventing module overload and improving longevity.
• Through-Hole Mounting (16DIP): Facilitates robust mechanical integration in legacy or prototyping designs.
• Robust Compliance: ROHS3 and EAR99 certified, ensuring global regulatory adherence.
• Not MSL-Rated: Suitable for non-moisture-sensitive environments, simplifying storage and handling.
