Download NEW4B PDF document NEW4B Once the side of the primary side feedback power factor correction LED controller Description NEW4B single-stage power factor correction (PFC), both isolated The primary side of the primary side feedback control and offline LED lighting controller and Achieve high power factor. Unique real-time current control method can be refined Correct by the side of the primary side feedback to control the LED current. By eliminating the need Secondary side feedback components and optocouplers so effectively simplify LED Lighting system design. Very low start-up current (Start-Up Current) quiescent current (Quiescent Current) reduces the overall power consumption and lighting High efficiency solution. . NEW4B improve system reliability and safety protection mode Sex. NEW4B voltage protection, short circuit protection, cycle-by-cycle currentRestrictions. Characteristic ●The real-time current control without secondary feedback ●Accurate constant current output mode ● Transpose Mode (TM) power factor correction ●Very low start-up current (10μA) ● Low quiescent current (1mA) ● Cycle-by-cycle over-current protection ● VCC pin over-voltage protection ● Output open-circuit protection ● Short-circuit protection ● SOT-26 package Application ●Solid-state lighting ●Industrial and commercial lighting ●Home lighting
