SS6640-50CSTR
1. 物料型号: - SS6640-XXCXXX,其中“XX”代表输出电压等级(27代表2.7V,30代表3.0V,33代表3.3V,50代表5.0V),“A”代表可调输出电压版本。

2. 器件简介: - SS6640是一款高效率的升压DC/DC转换器,适用于使用1至4节电池的场合。仅需三个外部组件即可提供2.7V、3V、3.3V或5V的固定输出电压。

3. 引脚分配: - VOUT:IC供电引脚,连接VOUT到控制器输出。 - CE:芯片使能引脚(高电平有效)。 - SW:内部N沟道MOSFET开关的漏极。 - COM:地端引脚。 - FB:输出电压可调引脚,VOUT电压由公式 \( \frac{R2}{R1}=\frac{V_{OUT}}{1.24}-1 \) 确定。

4. 参数特性: - 输出电压:根据不同型号,输出电压分别为2.7V、3V、3.3V和5V。 - 启动电压:典型值为0.8V至0.9V。 - 保持电压:为0.7V。 - 供电电流:在不同条件下,供电电流的最小值、典型值和最大值均有详细说明。

5. 功能详解: - SS6640采用脉冲频率调制(PFM)方案,优化了轻负载输出和低输入电压下的应用性能。与PSM模式相比,输出纹波和噪声更低。 - 具有节省电池寿命的关闭模式和可调输出版本。 - PFM控制电路以高达100kHz的开关速率运行,使得被动组件尺寸更小,适用于空间受限的应用。

6. 应用信息: - 适用于需要升压转换的便携式设备,如寻呼机、相机、无线麦克风、掌上电脑、电池备份电源和便携式仪器。

7. 封装信息: - 提供MSOP8和小型轮廓封装(SOP)两种封装类型。 - 封装的物理尺寸和引脚塑料SO封装(SOT)的尺寸均在文档中有详细描述。
