description

LTC ® 1143系列是一个双路，降压型开关稳压控制器，具有自动突发模式™操作在低输出电流时保持高效率。 该装置是由两个独立的稳压器模块，每个模块驱动外部功率MOSFET的开关频率高达400kHz，采用恒定关断时间电流模式架构。 固定和可调电压可供选择。

经营两个稳压器的电流是用户可编程的，通过一个外部电流检测电阻。 宽广的输入电压范围允许从4V至14V（16V最大）的运作。 LTC1143L和LTC1143L - ADJ延长运行至VIN= 3.5V。 100％占空比提供低压差调节，外部MOSFET和电感器和电流检测电阻target电阻的R DS（ON），只能由有限的。

LTC1143系列是为需要在少量的电路板空间，在宽负载电流范围的高转换效率的双输出电压应用的理想选择。
