The combination of optimized circuit design and bipolar fracture technology with high performance and price ratio can ultimately save the overall cost. The power controller can be applied to a typical flyback circuit topology to form a simple AC / DC transformer. The starting circuit inside the IC is designed as a unique current suction mode, which can start to use the power switch tube itself, which reduces the significant amplification effect of the power consumption starting resistance; when the output power is low, the IC will automatically reduce the working frequency, so the standby power consumption becomes extremely low. At the same time, the functions of overload and saturation prevention perfect the integrated circuit, which can avoid some abnormal states, such as overload, transformer saturation, and output short circuit, so as to improve the internal reliability of the power supply. Current limit and clock frequency can be set by external components. Now standard packaging and environmental protection lead-free packaging, in line with the European standard DIP 8 supply.

产品概述 返回TOP
CXAC8503系列是高性能电流模式PWM控制器，专为AC / DC变压器具有较高的性能和价格比而设计，它提供了12W的连续输出功率，85V和265V之间的宽电压范围内，峰值输出功率可高达18W。优化合理的电路设计和双极性骨折技术具有很高的性能和价格比的组合最终节约整体成本。功率控制器可以应用到典型的反激电路拓扑，以便形成一个简单的AC / DC变压器。 IC内部的启动电路被设计为一种独特的电流吸入方式，它可以开始利用功率开关管本身，这减轻了功耗启动电阻显着的放大作用;当输出功率较低，IC将自动降低工作频率，因此，待机功耗变得极低。同时，过载和饱和防止的功能完善集成电路，它可以避开某些异常状态，例如过载，变压器饱和，和输出短路，从而提高电源的可靠性的内部。电流限制和时钟频率可以设置由外部组件。现在的标准封装及环保无铅封装，符合DIP8欧洲标准供给。
