AOZ7111 Overview
Key Specifications
Package: LSOP
Mount Type: Surface Mount
Pins: 8
Max Voltage (typical range): 18 V
Description
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.
Key Features
- No AC input voltage sensing requirement
- AC Fault Detect™ makes system more robust
- Maximum switching frequency limitation
- Additional OVP detection pin
- Output over-voltage / open-feedback protection and disable function
