MP4059 - Single-Stage PFC Flyback Controller

Description

The MP4059 is a single-stage PFC flyback controller for LED deep-dimming applications.

The MP4059 can regulate constant current to an LED load over a wide 1% to 100% dimming range without flickering or shimmering.

Features

  • enhance system reliability and safety greatly. Protection features include over-voltage protection (OVP), short-circuit protection (SCP), primary-side over-current protection (OCP), brown-out protection, cycle-by-cycle current limit protection, under-voltage lockout (UVLO), and auto-restart over-temperature protection (OTP). The MP4059 is available in a SOIC-8 package.

The Future of Analog IC Technology MP4059 Single-Stage PFC Flyback Controller with Primary-Side Feedback, for LED Drivers Down to 1% Dimming DESCRIPTION The MP4059 is a single-stage PFC flyback controller for LED deep-dimming applications. The MP4059 can regulate constant current to an LED load over a wide 1% to 100% dimming range without flickering or shimmering. The MP4059 is a primary-side controller without any secondary-side feedback components or optocouplers, simplifying the LED driver design significantly. The MP4059 integrates power factor correction and works in valley switching mode to achieve high efficiency. The MP4059 achieves ultra-low power consumption and can shut off the LED in standby mode, making it suitable for smart lighting applications.
