Description
The FL7930B is an active power factor correction
(PFC) controller for boost PFC applications that
operate in critical conduction mode (CRM). It uses a
voltage-mode PWM that compares an internal ramp
signal with the error amplifier output to generate a
MOSFET turn-off signal. Because the voltage-mode
CRM PFC controller does not need rectified AC line
voltage information, it saves the power loss of an input
voltage sensing network necessary for a current-mode
CRM PFC controller.
FL7930B provides over-voltage protection (OVP), open-
feedback protection, over-current protection (OCP),
input-voltage-absent detection, and under-voltage
lockout protection (UVLO). The additional OVP pin can
be used to shut down the boost power stage when
output voltage exceeds OVP level due to the resistors
that are connected at INV pin are damaged. The
FL7930B can be disabled if the INV pin voltage is lower
than 0.45 V and the operating current decreases to a
very low level. Using a new variable on-time control
method, total harmonic distortion (THD) is lower than in
conventional CRM boost PFC ICs.

Absolute Maximum Ratings
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.
The absolute maximum ratings are stress ratings only.

Notes:
1. When this pin is supplied by external power sources by accident, its maximum allowable current is 50 mA.
2. In case of DC input, the acceptable input range is -0.3 V~6 V: within 100 ns -10 V~6 V is acceptable, but
electrical specifications are not guaranteed during such a short time.
