Critical Conduction Mode PFC Controller
FAN7930 — Critical Conduction Mode PFC Controller April 2010 FAN7930 Critical Conduction Mode PFC Controller Features Description PFC Ready Signal The FAN7930 is an active power factor correction (PFC) controller for boost PFC applications that operate in Input Voltage Absent Detection Circuit critical conduction mode (CRM). It uses a voltage-mode Maximum Switching Frequency Limitation PWM that compares an internal ramp signal with the error amplifier output to generate a MOSFET turn-off Internal Soft-Start and Startup without Overshoot signal. Because the voltage-mode CRM PFC controller Internal Total Harmonic Distortion (THD) Optimizer does not need rectified AC line voltage information, it saves the power loss of an input voltage sensing network Precise Adjustable Output Over-Voltage Protection necessary for a current-mode CRM PFC controller. Open-Feedback Protection and Disable Function FAN7930 provides over-voltage protection, open- Zero Current Detector feedback protection, over-current protection, input- voltage-absent detection, and under-voltage lockout 150μs Internal Startup Timer protection. The PFC-ready pin can be used to trigger MOSFET Over-Current Protection other power stages when PFC output voltage reaches the proper level with hysteresis. The FAN7930 can be Under-Voltage Lockout with 3.5V Hysteresis disabled if the INV pin voltage is lower than 0.45V and Low Startup and Operating Current the operating current decreases to a very low level. Using a new variable on-time control method, THD is Totem-Pole Output with High State Clamp lower than the conventional CRM boost PFC ICs. +500/-800mA Peak Gate Drive Current Related Resources 8-Pin SOP AN-8035 — Design Consideration for Boundary Applications Conduction Mode PFC Using FAN7930 Adapter Ballast LCD TV, CRT TV SMPS Ordering Information Operating Packing Part Number Temperature Top Mark Package Method Range FAN7930M Rail -40 to +125°C FAN7930 8-Lead Small Outline Package (SOP) FAN7930MX Tape & Reel © 2010 FAN7930 • Rev. 1.0.1
