UCC28950PW Full-bridge Controller Description
The UCC28950 enhanced phase-shifted controller expands on Texas Instruments' industry-standard UCx895 phase-shifted controller family, offering best-in-class efficiency in today's high-performance power systems. The UCC28950 implements advanced full-bridge control as well as active control of the synchronous rectifier output stage.
The primary-side signals allow for programmable delays to ensure ZVS operation over a wide load current and input voltage range, while the load current naturally tunes the switching delays of the secondary-side synchronous rectifiers, maximizing overall system efficiency.
The UCC28950 also includes a burst mode and dynamic SR on/off control when transitioning into and out of Discontinuous Current Mode (DCM) operation, ensuring ZVS operation is extended down to much lighter loads.
