I’ll apply the broader pin function groups directly to the part pins, then verify the updated grouping.

Applied the general functional pin groups to all 24 terminals and verified them.
Groups used: Power, Ground, Control / Feedback, Timing / Configuration, Current Sense, Synchronization, and Outputs. Each physical pin is assigned to exactly one group.

UCC28950TPWRQ1 Engineering Specifications
General Description
The UCC28950TPWRQ1 is an automotive-qualified phase-shifted full-bridge controller manufactured by Texas Instruments. It is specifically designed for high-efficiency isolated DC-to-DC power conversion systems requiring advanced control, high power density, and reliable operation in demanding automotive and industrial environments.
The device implements phase-shifted pulse-width modulation control with programmable dead-time management to achieve zero-voltage switching across a wide load range. This soft-switching architecture significantly reduces switching losses, improves overall efficiency, minimizes electromagnetic interference, and enables higher switching-frequency operation.
The controller integrates comprehensive protection and monitoring functions, including current limiting, overvoltage protection, soft-start control, and fault management. Its flexible architecture supports a wide variety of isolated power-supply topologies used in electric vehicles, onboard charging systems, telecommunications infrastructure, industrial power supplies, and high-performance DC-DC converters.
Qualified to automotive reliability standards, the device is suitable for mission-critical applications requiring long-term operational stability and robust power-conversion performance.
