Description

This reference design generates an isolated 12V/160W 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. Texas Instruments CSD18531Q5A synchronous rectifiers allow this design to achieve over 92% 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.
