PMP41140 Simplified Block Diagram Simplified Block Diagram
Note:

The simplified block diagram demonstrates a whole AD-DC isolated system including Totem-pole PFC stage and Asymmetrical Half Bridge stage, F28P55x series DSP has capability to control both these two stages in one device. PMP41140 reference design board only demonstrates the AHB stage operating for evaluation.
