The TX2304 Series is a Synchronous step-up DC/DC Converter with PFM Control.With the TX2304 Series, a step-up switching DC/DC converter can be configured by using an external coil 、 capacitor. The built-in MOSFET is turned off by a protection circuit when the voltage at the LX pin exceeds the limit to prevent it from being damaged.

    TX2304系列是一个同步加速直流/直流转换器与PFM控制。与TX2304系列，可以配置一个升压开关直流/直流转换器，通过使用一个外部线圈、电容器。当LX引脚处的电压超过极限时，内置的MOSFET会被一个保护电路关闭，以防止其被损坏。
