Description

The PMP30092 reference design uses the UCC28633 high power flyback converter to generate an isolated output (27V @ 6A). The UCC28633 operates in both CCM (continuous conduction mode) and DCM (discontinuous conduction mode). Primary side regulation eliminates the need for an opto-coupler and reduces the total component count. The secondary side wake-up controller UCC24650 enables excellent load transient performance and low standby power.

Features
  • Wide AC input range (85VAC - 264VAC)
  • Low standby power
  • Excellent transient performance
  • Test report available
