PF6771 is a power supply controller that integrates both PFC stage and LLC stage, and it also features digital control capabilities. On the PFC side, it supports two control modes: CRM (Critical Conduction Mode) and DCM (Discontinuous Conduction Mode). In the LLC stage, it employs a asymmetrical LLC architecture, specifically a half-bridge LLC, providing dual regulated output voltages. Additionally, it offers dual feedback loops, allowing independent control of these output voltages.
