数据: TPS6240x 2.25-MHz 400-mA and 600-mA Dual Step-Down Converter In Small 3-mm x 3-mm VSON Package 数据表
TPS6240x系列器件是针对电池供电的便携式应用而优化的同步双路降压DC-DC转换器。这些器件提供两个独立的输出电压轨,由1节锂离子电池或3芯镍氢/镍电池供电。这些器件也适用于标准的3.3V或5V电压轨。
TPS62400的输入电压范围为2.5 V至6 V,非常适合为智能手机等便携式应用提供电源。 ,PDA和其他便携式设备。
使用EasyScale串行接口,可在运行期间修改输出电压。固定输出电压版本TPS62401,TPS62402,TPS62403和TPS62404支持单引脚控制的简单动态电压调节,适用于低功耗处理器。
TPS6240x工作在2.25 MHz固定开关频率并进入电源在轻负载电流下保存模式操作,以在整个负载电流范围内保持高效率。对于低噪声应用,可以通过将MODE /DATA引脚拉高来强制器件进入固定频率PWM模式。在关断模式下,典型的电流消耗降至1.2μA。这些器件允许使用小型电感器和电容器来实现小尺寸解决方案。
TPS62400采用10引脚无引脚封装(3 mm×3 mm VSON)
