FAN7530
Critical Conduction Mode PFC Controller
Features
Applications
Related Application Notes
Description
The FAN7530 is an active power factor correction (PFC) controller for 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. Since the voltage mode CRM PFC controller does not need rectified AC line voltage information, it saves the power loss of the input voltage sensing network necessary for the current mode CRM PFC controller.
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.
Absolute Maximum Ratings
The “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed. The device should not be operated at these limits. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum ratings. TA=25°C, unless otherwise specified.
