AOZ7111 Datasheet (Alpha & Omega Semiconductors) - Critical Conduction Mode PFC Controller

AOZ7111, Critical Conduction Mode PFC Controller

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
