ML4821
Power Factor Controller
Features
• Average current sensing for lowest possible harmonic distortion • Average line compensation with brown-out control • Precision buffered 5V reference • 1A peak current totem-pole output drive • Overvoltage comparator eliminates output “runaway” due to load removal • Wide common mode range in current sense comparators for better noise immunity • Large oscillator amplitude for better noise immunity • Output driver internally limited to 17V • “Sleep mode” shutdown input
General Description
The ML4821 provides complete control for a “boost” type power factor correction system using the average current sensing method.
