The FL7740MX from On Semiconductor is a PWM controller designed for primary-side regulation and power factor correction in AC-DC conversion applications. It provides accurate Constant Voltage (CV) regulation in steady-state conditions with a precision of less than ±3% and handles load transients with regulation within ±10%.
The controller features a wide universal input voltage range from 90 VAC to 305 VAC, making it suitable for global applications. It boasts a fast startup time of less than 0.2 seconds and achieves low standby power, less than 0.3 W, which is beneficial for smart lighting systems. The device also supports power factor higher than 0.9 even at half load conditions when the PF optimizer is enabled.
Integrated protections include Overload, Output Short Protection, Output Over Voltage Protection, Output Diode Short Protection, and Sensing Resistor Short & Open protection, enhancing system reliability. The FL7740MX is supplied in a 10-SOIC package and is designed for surface mounting.
Typical applications include LED lighting systems, AC-DC adapters for TVs and monitors, and other off-line appliances requiring power factor correction.
