Power Factor Correction ICs
-
Status:Available
FA5612 is a control IC for power factor correction converters. It achieves low power consumption by using a high-voltage CMOS process. Since it uses an average value current control method, it is capable of stable operation and can easily achieve a power factor of 99% or higher. In addition, it can control the DC output voltage over a wide range of loads from the rated load down to no-load. Furthermore, the line filter can be simplified by incorporating a proprietary switching frequency spread function.
Features
- Built-in proprietary switching frequency spread function
- Switching frequency: selectable between spread and fixed (60 kHz, 65 kHz)
- High-precision current detection: 0.5 V ± 5%
- Prevents noise using a dynamic OVP circuit
- Achieves low power consumption by using a high-voltage CMOS, 2 mA (typ.) during operation
- Capable of directly driving a power MOSFET, output peak current: source 1.5 A /sink 1.5 A
- Stops circuit operation even when an abnormality occurs in the output voltage detection unit using an FB short-circuit detection circuit
- Built-in low voltage malfunction prevention circuit (9.6 V ON / 9 V OFF)
- Package: SOP-8,
