NCP105数据手册集成电路（IC）的ACDC转换器离线开关规格书PDF

描述 Description

The NCP105 is 150 mA LDO that provides a very stable, accurate voltage with low noise suitable for space constrained, noise sensitive applications. In order to optimize performance for battery operated portable applications, the NCP105 employs the dynamic quiescent current adjustment for very low IQ consumption at no−load.The NCP105 is offered in both a small XDFN-4 1 mmx1 mm, 0.4mm Thin package as well as in a standard TSOP5 package.

简介

NCP105属于集成电路（IC）的ACDC转换器离线开关。由制造生产的NCP105AC DC 转换器，离线开关该系列是元器件级控制产品，用于构建将交流市电转换为直流电（通常电压大幅降低）的设备。集成和未集成系统主要开关元件的器件均包括在内。由于高输入输出电压比，以及此类系统中通常需要隔离，这些器件通常与外部变压器配合使用。尽管通常使用定制变压器来实现此用途，但也有许多专门用于此用途的库存产品，请参见“开关转换器，SMPS 变压器”标题。
