SS6640-33CSTB
1. 物料型号: - 型号为SS6640,提供固定输出电压版本(2.7V、3.0V、3.3V、5.0V)和可调输出电压版本。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。采用脉冲频率调制(PFM)方案,在轻负载输出和低输入电压下提供优化性能。

3. 引脚分配: - VOUT:IC供电引脚,连接到控制器输出。 - 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,输出电压计算公式为:\( \frac{R2}{R1}=\frac{V_{OUT}}{1.24}-1 \)。

4. 参数特性: - 供电电压、FB引脚电压、SW引脚开关电流、工作温度范围(0°C至85°C)、存储温度范围(-5°C至150°C)、焊接引脚温度(10秒内60°C)。

5. 功能详解: - SS6640 PFM转换器集成了开关模式控制器、N沟道功率MOSFET、精密电压参考和电压检测器。提供极低的静态电流、高效率和非常低的门限电压,确保低电池电压下(典型值0.8V)启动。

6. 应用信息: - 适用于需要最大化电池寿命的便携式产品,通过仅在需要时切换以减少开关损失。PFM转换器每周期传递一定量的能量,并通过调制开关频率来调节输出电压。

7. 封装信息: - 提供MSOP8封装,具体尺寸参数在PDF文档中有详细描述。
