FL7930

Single-Stage Flyback and Boundary-Mode PFC

Controller for Lighting

Features

Description

Additional PFC-Ready Function (FL7930C Only)

The FL7930 is an active Power Factor Correction (PFC)

controller for low-to high-power lumens 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.

Input-Voltage-Absent-Detection Circuit

Maximum Switching Frequency Limitation

Internal Soft-Start with Overshoot Prevention

Internal Total Harmonic Distortion (THD) Optimizer

Precise Adjustable Output Over-Voltage Protection

Additional OVP Detection Pin (FL7930B Only)

Open-Feedback Protection and Disable Function

Zero-Current Detector

FL7930 provides over-voltage, open-feedback, over-

current, input-voltage-absent detection, and under-

voltage lockout protections. The FL7930 can be

disabled if the INV pin voltage is lower than 0.45V and

the operating current decreases to a very low level.

Using a new variable on-time control method, THD is

lower than the conventional CRM boost PFC ICs.

150µs Internal Startup Timer

MOSFET Over-Current Protection (OCP)

Under-Voltage Lockout with 3.5V Hysteresis

Low Startup and Operating Current

The FL3930B provides an additional OVP pin that can

be used to shut down the boost power stage when

output voltage exceeds OVP level due to damaged

resistors connected at the INV pin. The FL7930C

provides a PFC-ready pin can be used to trigger other

power stages when PFC output voltage reaches the

proper level (with hysteresis).
