RVCC pin is the regulated 12-V supply which can supply up to 100-mA current. The regulated rail is used to supply the PFC, and LLC gate driver. RVCC has under voltage lock out (UVLO) function. If during normal operation, RVCC voltage is less than RVCCUVLO threshold. It is treated as a fault and the system will enter FAULT state. Details about the FAULT handling will be discussed in the section.
