NCP1252ADR2G规格书详情
The NCP1252 controller offers everything needed to build cost−
effective and reliable ac−dc switching supplies dedicated to ATX
power supplies. Thanks to the use of an internally fixed timer,
NCP1252 detects an output overload without relying on the auxiliary
Vcc. A Brown−Out input offers protection against low input voltages
and improves the converter safety. Finally a SOIC−8 package saves
PCB space and represents a solution of choice in cost sensitive project.

• Ready for Updated No Load Regulation Specifications
• SOIC−8 and PDIP−8 Packages
• These are Pb−Free Devices
Typical Applications
• Power Supplies for PC Silver Boxes, Games Adapter...
• Flyback and Forward Converter
NCP1252ADR2G属于集成电路(IC) > AC DC 转换器,离线开关。安森美半导体公司制造生产的NCP1252ADR2GAC 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。
