| Description | IC REG CTRLR FULL-BRIDGE 24TSSOP |
| Datasheet | UCC28950PWR Datasheet |
The Texas Instruments UCC28950PWR is a highly advanced and versatile phase-shifted full-bridge controller designed for high-efficiency, high-power-density DC/DC converters. This innovative component is engineered to facilitate the creation of power supplies that require a small form factor without compromising on performance and reliability.
At the heart of the UCC28950PWR is its ability to provide precise control over power conversion processes, thanks to its innovative phase-shifted control method. This technique allows for zero-voltage switching (ZVS) over a wide range of load conditions, significantly reducing switching losses and enhancing overall system efficiency. As a result, power supply designers can achieve efficiency levels that meet or exceed rigorous industry standards, such as the 80 PLUS certification for computer power supplies.
The device is housed in a compact 24-pin TSSOP (Thin Shrink Small Outline Package) that offers a space-saving solution for densely packed circuit boards. The UCC28950PWR incorporates a range of features that simplify the design of complex power systems, including programmable switching frequency, soft start, and shutdown functions. These features provide designers with the flexibility to tailor the controller to a wide variety of applications, ensuring optimal performance across different use cases.
One of the key advantages of the UCC28950PWR is its dual-output drive stages that enable synchronous rectification. This feature further optimizes efficiency by minimizing diode conduction losses typically associated with rectification processes. Additionally, the controller offers protection features such as overcurrent, overvoltage, and undervoltage lockout, safeguarding the power supply and the end application from potential damage due to abnormal operating conditions.
With its robust feature set and Texas Instruments’ commitment to quality, the UCC28950PWR is an excellent choice for designing power supplies in server, telecom, and industrial applications where efficiency and power density are critical. Whether you’re creating a power supply for demanding data centers or for sensitive telecom equipment, the UCC28950PWR provides the reliability and performance needed to meet the challenges of modern power conversion requirements.
