FL7930CMX Overview
Key Specifications
Package: SOP
Mount Type: Surface Mount
Pins: 8
Operating Voltage: 14 V
Description
The FL7930C 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.
Key Features
- PFC-Ready Signal
- VIN-Absent Detection
- Maximum Switching Frequency Limitation
- Internal Soft-Start and Startup without Overshoot
- Internal Total Harmonic Distortion (THD) Optimizer
- Precise Adjustable Output Over-Voltage Protection
- Open-Feedback Protection and Disable Function
- Zero-Current Detector (ZCD)
- 150 μs Internal Startup Timer
- MOSFET Over-Current Protection (OCP)
