PFM控制、升压同步整流DC/DC转换器

XC9140系列是升压同步整流DC/DC转换器，内置支持陶瓷电容的0.6Ω N-ch驱动器Tr和0.65Ω P-ch同步整流开关Tr。采用PFM控制实现低消耗电流，适用于重视高效率的便携式机器。
当输出电压为3.3V，负载电流为1mA时，输入电压可以从VIN=0.9V开始启动，该产品可用于以单节碱性或镍氢电池启动的机器。

另外可以选择附带UVLO(Undervoltage Lock Out)功能的产品，当输入电压过低时，停止IC工作，防止电池液体泄漏。 标准产品的UVLO 解除电压为 1.65V，2.2V，另外也可以定制 1.65V ~ 2.15V 范围内0.05V间隔的产品。
