FA1A50 1A50 SOP8  original

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.

Switching Power Supplies

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
