概览

  The NCL30486B is a high PF Single stage Constant Current and Constant Voltage PSR PWM controller for Flyback/ Buck-Boost/ Sepic/ Boost. This controller operates in a QR mode to provide high efficiency. Thanks to a novel control method, the device is able to tightly regulate a constant LED current from the primary side. This device is providing very deep analog dimming output current with two dedicated dimming control input pin – ADIM and PDIM.
