数据: TPS53315 12-A Step-Down Regulator with Integrated Switcher 数据表
TPS53315是一款D-CAP™模式,12-A同步切换器,集成了MOSFET。它的设计易于使用,外部元件数量少,封装电源系统小。
该器件具有单轨输入支持,一个19mΩ和一个7mΩ集成MOSFET,精度为1% ,0.6 V基准电压源和集成升压开关。竞争特性的示例包括:最大效率高于96%,输入电压范围为3 V至15 V,外部元件数量极低,D-CAP™模式控制可实现超快速瞬态,可选择自动跳过和PWM操作,内部软启动控制,频率可调,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,输出电压范围电压为0.6 V至5.5 V。
TPS53315采用5 mm×7 mm 40引脚VQFN封装,额定温度范围为-40°C至85°C。
