1 / 15 page  Rev. 1.0 January 2013 www.aosmd.com Page 1 of 15 AOZ7111 Critical Conduction Mode PFC Controller General 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 current- mode CRM PFC controller. The AOZ7111 minimizes the number of external components by integrating safety features that make it an excellent choice for designing robust PFC stages. The AOZ7111 is available in a SO-8 package and it is rated over a -40°C to +125°C ambient temperature range. 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 Internal closed loop soft-start Dynamic OVP function Non-linear gain error amplifier enable fast line and load transient response No need for the auxiliary winding with minus current detection (ZCD) 150µs internal start-up timer MOSFET over-current protection and inductor saturation protection Under-voltage lockout with hysteresis Lower startup and operating current +300mA / -800mA peak gate drive current Thermal shutdown SO-8 package Applications Adapter / ballast LCD TV / LED TV SMPS Typical Application OVP GND OUT INV CT VCC COMP CS AOZ7111 + VCC AC Line Filter VOUT + Figure 1.
