SS6640-ACOTB
1. 物料型号: - 型号为SS6640,是一个升压型DC/DC转换器。 - 订购信息中提到了不同版本的型号,例如SS6640-27COTR表示2.7V版本,MSOP8封装,卷带包装。

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。 - 只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。 - 采用脉冲频率调制(PFM)方案,适用于轻负载输出和低输入电压的应用。

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-MOSFET开关的漏极。 - COM:地终端,必须低阻抗,直接焊接到地平面。 - FB:输出电压可调引脚,VOUT电压由公式确定。

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。 - 输入电压:最大输入电压为8V。 - 启动电压:在1mA负载下,启动电压为0.9V。 - 保持电压:在1mA负载下,保持电压为0.7V。 - 供电电流:根据不同型号,供电电流有所不同。

5. 功能详解: - SS6640通过PFM控制电路工作,在100kHz的最大开关频率下,可实现更小的被动组件尺寸。 - 具有节省电池寿命的关闭模式和可调输出版本。 - PFM转换器通过调节开关频率来控制输出电压,开关频率取决于负载、输入电压和电感值。

6. 应用信息: - 适用于需要升压转换的便携式产品,如传呼机、相机、无线麦克风、口袋型组织器、电池备份电源和便携式仪器。

7. 封装信息: - 封装类型包括MSOP8和小外形封装(SOP)。 - 提供了MSOP8和SO封装的物理尺寸图。
