Power Factor Correction ICs
-
Status:Available
The FA1A50N is a control IC for configuring a critical-mode power factor correction converter. It achieves low power consumption by using a high-voltage CMOS process. It also has a redundant overvoltage protection function and FB short-circuit protection circuit.
Features
- Capable of low standby power by disabling input voltage detection
- High-precision current detection: 0.6 V ± 2%
- Improves efficiency under light loads using a frequency reduction function
- Reduces noise using an overshoot reduction function and dynamic OVP circuit
- Achieves low power consumption by using a high-voltage CMOS process
- Startup of 500 μA (typ), 1.5 mA (typ) during operation
- Capable of directly driving power MOSFET, output peak current: source 0.5 A/sink 1 A
- Prevents overvoltage and protects the output electrolytic capacitor using a redundant overvoltage protection circuit, even when an abnormality occurs in the output voltage detection line.
- Stops circuit operation when the output voltage detection unit detects an abnormality using an FB short-circuit detection circuit
- Built-in low voltage malfunction prevention circuit (9.6 V ON/8.8 V OFF)
- Restart timer
- Package: SOP-8
