KOA Speer Electronics 的电阻器系列具有增强的 ESD 保护功能
2019-9-5SG3842G-BiCMOS工艺的绿色模式PWM控制器
SG348xG系列电流模式PWM控制器结合了高性能与绿色模式省电功能。 SG348xG控制器是完全针到针与双极UC384X器件兼容，但他们已经改进了的特性和功能。 SG384xG系列控制器是兼容的BiCMOS工艺制造工艺，使使用低启动电流和工作电流。这一功能进一步提高电源转换效率。最小已经启动电流降低至5uA，和最小工作电流已经降低到5mA。每个SG384xG具有摆率控制高电流图腾柱输出，非常适合用于驱动电源MOSFET的同时保持EMI的低。通常电流检测的传播延迟为50ns，产生显着更有效的常数电源保护。在正常操作过程中，SG384xG控制器充当一个固定频率PWM控制器。 “通过改变PWM频率
2012-11-25SG6848-低成本的绿色模式PWM控制器，用于回扫转换器
这种高度集成的PWM控制器提供几个特殊的增强设计，以满足低待机低功率SMPS的电力需求。为了尽量减少待机功耗，专有的绿色模式功能，提供关断时间调制，以线性降低轻负载下的开关频率条件。这绿色模式功能，使电源供应很容易满足，即使在严格的的电源保护的要求。的BiCMOS制造工艺使减少在启动电流5uA，工作电流2毫安。为了进一步提高节能，大启动电阻可以采用。内置同步斜率补偿保证了稳定的峰值电流模式控制。专有的内部补偿规定在一个通用AC输入一个恒定的输出功率限制范围（90VAC至264VAC）。脉冲通过脉冲电流限制，确保安全运行，即使在短路。为了保护外部功率MOSFET损坏供
