摘　　要：实现了±15V、±5V和3.3V多级电压同时输出的电源适配卡的设计。直流稳压电源是电子系统中很重要的一部分,其作用是为电子系统提供不同大小的稳定的电能。利用具有隔离稳压功能的HDW5-24D15A1和WD10-24D05B1的DC-DC电压转换模块和正向低压降稳压器LM1117,设计了满足一定功耗的多级DC-DC_±15V、DC-DC_±5V、DCDC_3.3V的电源适配卡,使其满足某些电子电路系统中对于不同直流电压的需求。This paper realizes of±15V,±5V and 3.3V power supply at the same time adapter while the output voltage of the multi-stage power adapter design.DC power supply is an electronic system in a very important part of its role is to provide a stable power electronic systems of different sizes.In this paper,a separate regulator function HDW5-24D15A1WD10-24D05B1 and a DC-DC converter module and the forward voltage low dropout voltage regulator LM1117,is designed to meet the power consumption of certain multi-level DC-DC_±15V,DC-DC_±5V,DC-DC_3.3V power adapter.
