Dual-Output, Critical Conduction Mode PFC Controller
FAN7528 Dual-Output, Critical Conduction Mode PFC Controller February 2007 FAN7528 Dual-Output, Critical Conduction Mode PFC Controller Features Description Low Total Harmonic Distortion (THD) The FAN7528 is an active power factor correction (PFC) controller for boost PFC applications that operates in Dual Output Voltage Control critical conduction mode (CRM). It uses voltage mode Precise Adjustable Output Over-Voltage Protection PWM that compares an internal ramp signal with the Open-Feedback Protection and Disable Function error amplifier output to generate MOSFET turn-off sig- Zero Current Detector nal. Because the voltage mode CRM PFC controller does 160µs Internal Start-up Timer not need the rectified AC line voltage information, it can MOSFET Over-Current Protection save the power loss of the input voltage sensing network necessary for the current mode CRM PFC controller. Under-Voltage Lockout with 3.5V Hysteresis Low Start-up (40µA) and Operating Current (1.5mA) The FAN7528 provides the dual-output voltage control function without the AC line voltage sensing for adapter Totem-Pole Output with High State Clamp applications. It changes the PFC output voltage accord- ±400mA Peak Gate Drive Current ing to the AC line voltage. 8-Pin DIP or 8-Pin SOP It provides protection functions such as over-voltage pro- Applications tection, open-feedback protection, over-current protec- tion, and under-voltage lockout protection. The FAN7528 Adapter can be disabled if the INV pin voltage is lower than 0.45V and the operating current decreases to 65µA.
