LMR14010A 具有高效 Eco-Mode 的 4V 至 40V、1A 降压转换器

描述

LMR14010A是一款PWM直流/直流降压稳压器。该器件具有4V至40V的宽输入范围，因此适用于从工业到汽车的各种应用.1μA的超低关断电流可延长电池寿命。工作频率固定在0.7MHz，从而允许使用小型外部组件，同时能够最大程度地降低输出纹波电压。在内部实现了软启动和补偿

LMR14010A针对高达1A的负载电流进行了优化。它具有0.765V的标称反馈电压。

该器件具有内置的保护功能，如逐周期电流限制，热感应以及在功率耗散过大时关断.LMR14010A采用薄型TSOT-6L封装（2.9mm×1.6mm×0.85mm）。
