MP4059 Single-Stage PFC Flyback Controller with Primary-Side Feedback, for LED Drivers Down to 1% Dimming The Future of Analog IC Technology DESCRIPTION FEATURES The MP4059 is a single-stage PFC flyback 1% to 100% PWM Dimming Range controller for LED deep-dimming applications. Ultra-Low Standby Loss, Typically Less than The MP4059 can regulate constant current to an 50mW at 230V AC LED load over a wide 1% to 100% dimming Universal Input range without flickering or shimmering. The Fast Start-Up MP4059 is a primary-side controller without any No Flicker secondary-side feedback components or Low Audible Noise optocouplers, simplifying the LED driver design Valley Switching Mode for Good Efficiency significantly. The MP4059 integrates power Good PF (Typically >0.9) factor correction and works in valley switching Primary-Side Over-Current Protection mode to achieve high efficiency. (OCP) The MP4059 achieves ultra-low power Output Over-Voltage Protection consumption and can shut off the LED in (OVP)/Short-Circuit Protection (SCP) standby mode, making it suitable for smart Under-Voltage Lockout (UVLO) lighting applications. Thermal Shutdown (160C/100C) Available in a SOIC-8 Package The MP4059s multiple protection features enhance system reliability and safety greatly. APPLICATIONS Protection features include over-voltage LED PWM Dimming protection (OVP), short-circuit protection (SCP), All MPS parts are lead-free, halogen-free, and adhere to the RoHS primary-side over-current protection (OCP), directive.
