UCC2897ARGPT相关的参考设计

  • 18Vdc-72Vdc Input, 12V/10A Active Clamp Forward, 1/4 Brick - PMP8861 - TI Tool Folder
    This reference design generates a 12V/10A output from a wide range 18V to 72V telecom input. The UCC2897A controls an active clamp forward converter power stage. The low gate charge and low RDSon of the CSD18533Q5A, implemented as a synchronous rectifier, provides for a highly efficient design. This design is laid out in a standard quarter brick footprint and achieves efficiencies near 95%.
  • 220V-400VDC Input, 5V/100W Active Clamp Forward - PMP7413 - TI Tool Folder
    This reference design generates an isolated 5V/100W output from a high voltage DC input. This design is intended to operate from the output of PFC front end regulator. The UCC2897A is used to control an active clamp forward converter. Self-driven synchronous rectifiers allow for 91% efficiency. An accurate current limit is provided by directly sensing the output current. A clock pulse output is also provided for synchronizing with other converters.
