数据: 具有 Eco-mode™ 的 0.5A,60V 降压 SWIFT™ DC/DC 转换器 数据表 (Rev. B)
TPS54060A器件是一款带有集成型高侧MOSFET的60V,0.5A,降压稳压器。电流模式控制提供了简单的外部补偿和组件选择的灵活性。一个低纹波脉冲跳跃模式将无负载的稳定输出电源电流减小至116μA。采用使能引脚可将停机模式的电源电流降低至1.3μA(此时,使能引脚为低电平)。
欠压闭锁在内部设定为2.5V,但可采用使能引脚将之提高。输出电压启动斜坡受控于缓慢起动引脚,该引脚还可以通过配置来控制排序/跟踪。一个开漏电源正常信号表示说明第二段中的输出94%至107%的范围内。
宽开关频率范围允许对效率及外部组件尺寸进行优化。频率折返和热关断功能在过载情况下对部件实施保护。
