LMR14006 SIMPLE SWITCHER 40 V 600 mA Buck Regulator With High Efficiency Sleep Mode 数据表 
LMR14006是一款PWM DC /DC降压（降压）稳压器。它具有4 V-40 V的宽输入范围，适用于从工业到汽车的各种应用，可用于来自未调节电源的功率调节。在休眠模式下，稳压器的待机电流为28μA，适用于电池操作系统。超低1μA电流可在关断模式下进一步延长电池寿命。工作频率固定为1.1 MHz（X版本）和2.1 MHz（Y版本），允许使用小型外部元件，同时仍能具有低输出纹波电压。软启动和补偿电路在内部实现，这些允许器件与最小化的外部元件一起使用。 LMR14006针对高达600 mA的负载电流进行了优化，具有0.765 V的典型反馈电压。该器件具有内置保护功能，如逐脉冲电流限制，热感应和功耗过大导致的关断。 LMR14006采用扁平TSOT-6L封装。
