TX2304 Description/概述：
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系列是一個同步加速直流/直流轉換器與PFM控制。與TX2304系列，可以配置一個升壓開關直流/直流轉換器，通過使用一個外部線圈、電容器。當LX引腳處的電壓超過極限時，內置的MOSFET會被一個保護電路關閉，以防止其被損壞。
