FAN7530 Power Factor Controller IC (PFC)
৳ 120.00
The FAN7530 is an active power factor correction controller for the boost PFC applications, operates in critical conduction mode and voltage mode PWM that compares an internal ramp signal with the error amplifier output to generate MOSFET turn-off signal.
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 net-work necessary for the current mode CRM PFC control-ler.FAN7530 provides many protection functions such as over voltage protection, open-feedback protection, over-current 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 to65µA. Using a new variable on-time control method, THD is lower than the conventional CRM boost PFC ICs.
