STR-A6151M集成电路（IC）的ACDC转换器离线开关规格书PDF中文资料

STR-A6151M属于集成电路（IC）的ACDC转换器离线开关。由三垦电气株式会社制造生产的STR-A6151MAC 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。

General Descriptions

The STR-A6100 series are power ICs for switching power supplies, incorporating a MOSFET and a current

mode PRC controller IC. PRC (Pulse Ratio Control) controls on-time with fixed off-time.

The IC includes a startup circuit and a standby function to achieve the low standby power. The rich set

of protection features helps to realize low component counts, and high performance-to-cost power supply.
