10 / 21 page  FUSB3307 www.onsemi.com 10 Application Information FUSB3307 has the entire PD Device Policy Manager (DPM), PD Policy Engine, Protocol and PHY layers within hardware and it responds to all the messages typical for PD Power Sources. No external processor is needed and it is completely USB PD 3.0 with PPS compliant. Two Reference Design Examples Below are two reference design example applications of the FUSB3307. One is an AC/DC design on the secondary side of the offline design and the other is a DC/DC design where the FUSB3307 directly controls the DC/DC controller. In the descriptions that follow, both of these designs are discussed when describing the operation of the FUSB3307. Interspersed within these descriptions is how it relates to USB Power Delivery (PD) and Type C specifications. These are just two example designs since there are considerably more use cases of the FUSB3307 in reference designs for power source applications. For more information on specific design needs, please contact your ON Semiconductor field application engineers. Figure 5. Offline Reference Design Example Sync. Rec.
