FAN7530 Critical Conduction Mode PFC Controller Features Description „ Low Total Harmonic Distortion (THD) The FAN7530 is an active power factor correction (PFC) controller for the boost PFC applications that operates in critical conduction mode (CRM). It uses the voltage mode PWM that compares an internal ramp signal with the error amplifier output to generate MOSFET turn-off signal. Because the voltage mode CRM PFC controller does not need the rectified AC line voltage information, it can save the power loss of the input voltage sensing network necessary for the current mode CRM PFC controller. „ Precise Adjustable Output Over-Voltage Protection „ Open-Feedback Protection and Disable Function „ Zero Current Detector „ 150µs Internal Start-up Timer „ MOSFET Over-Current Protection „ Under-Voltage Lockout with 3.5V Hysteresis „ Low Start-up (40µA) and Operating Current (1.5mA) „ Totem Pole Output with High State Clamp „ +500/-800mA Peak Gate Drive Current FAN7530 provides many protection functions such as over voltage protection, open-feedback protection, overcurrent protection, and under-voltage lockout protection. The FAN7530 can be disabled if the INV pin voltage is lower than 0.45V and the operating current decreases to 65µA. Using a new variable on-time control method, THD is lower than the conventional CRM boost PFC ICs. „ 8-pin DIP or 8-pin SOP Applications „ Adapter „ Ballast „ LCD TV, CRT TV „ SMPS Related Application Notes „ AN-6027 - Design of Power Factor Correction Circuit Using FAN7530 Ordering Information Part Number Operating Temp.
