AOZ7111 Overview
The AOZ7111 is an active power factor correction (PFC) controller for boost PFC applications that operate in critical conduction mode (CRM). The device uses a voltage mode PWM which does not need rectified AC line voltage information, it saves the power loss of an input sensing network necessary for traditional currentmode CRM PFC controller. The AOZ7111 minimizes the number of external ponents by integrating safety.
