Description

The UCC28230, UCC28231 PWM bus controllers are optimized for use in high efficiency, high power density, unregulated intermediate bus converters. Topologies include push-pull, half-bridge and full-bridge. External drivers, such asthe UCC27200 120-V high-side/low-side drivers, can be used with this controller.

Low cost, small size and highly efficient solutions are provided by innovations such as:

  • Start-up frequency control circuit allowing small output inductor andthe ability to start with large intermediate bus capacitor.
  • Load depended off-time control set by user.

Additional 1-D control outputs can be used for primary winding clamping in self-driven output synchronous rectifier applications or as drive signals for the control-driven synchronous rectifier.
