Cxac85190 is a high performance off-line PWM controller, which is mainly used in small and medium power AC / DC chargers and adapters. It works in the original side sampling and adjustment

Cxac85190 is a high performance off-line PWM controller, which is mainly used in small and medium power AC / DC chargers and adapters. It works in the original side sampling and adjustment, and can save the interelectrode optocoupler and TL431. Its constant voltage and constant current control characteristics are shown in the figure below. The maximum output power can reach 15W.
In constant current control, the setting of current and output power can be adjusted by the sensing resistance Rs on the CS pin; in constant voltage control, high efficiency and high performance can be achieved by using the mixed working mode. In addition, good load adjustment characteristics can be obtained by using the internal conductor voltage drop compensation function. Under the condition of heavy load in constant current mode, the device works in PFM mode; medium load and light load, the device can work in PWM mode and frequency reduction mode.

   产品概述 返回TOPSMc嘉泰姆


        CXAC85190是一种高性能离线式PWM控制器,主要用于中小功率AC/DC充电器和适配器中。它工作于原边采样和调节,可省除极间光耦和TL431,其恒压和恒流控制特性说明如下图。最大输出功率可达15W。

在恒流控制时,其电流和输出功率的设定可由CS脚上的传感电阻Rs来调节;在恒压控制时,利用混合工作模式可以获得高效率和高性能。另外,利用内部的导线压降补偿功能可以得到良好的负载调整特性。在恒流模式重负载工作条件下,器件工作在PFM模式;中负载和轻负载,器件可工作在PWM模式和降频模式。SMc嘉泰姆

CXAC85190具有电源软启动控制和多种带自动恢复的有效保护,它包含逐周期电流限制,VDD过压保护,VDD钳位和欠压保护等。另外,CXAC85190还有优良的EMI性能和频率抖动控制特性,使用CXAC85190可获得高精确的恒压/恒流特性。SMc嘉泰姆
