Description

  • Reference design uses the UCC2894 to control an active clamp forward converter that generates an isolated 24V at 7A from a 380VDC input. This supply is intended to be used with a PFC boost front-end and requires an external 12V bias voltage for house-keeping on the primary side. This supply is over 91% efficient at full load
