TPS53314是一款具有集成型MOSFET的D-CAP™模式,6A同步开关。该器件专为实现易用性,低外部组件数和小型封装电源系统而设计。
该器件具有单轨输入支持能力,一个20-mΩ和一个7.5-mΩ集成型MOSFET,1%准确度,0.6 V基准以及集成型升压开关。部分具有竞争力的特性包括:> 96%的最大效率,3 V至15 V的宽输入电压范围,用于实现超快的瞬态响应的D-CAP™模式控制,可选的自动跳跃和PWM操作方式,内部软启动控制,可调频率且无需补偿。
转换输入电压范围为3 V至15 V,电源电压范围为4.5 V至25 V,而输出电压范围则为0.6 V至5.5 V。
TPS53314采用5 mm×7 mm 40引脚QFN封装,并具有-40°C至85°C的规定温度范围。
