芯片测试报告范文

芯片测试范文 Power bank 2000-4000 芯片测试报告 目的:鉴于原power bank2000-4000 芯片的输出电流不能满足不断升级、更新手机的需求,继而寻找高电流出去芯片,代替原有芯片,特针对此芯片芯片进行测试,为今后的更改做好铺垫 。 测试工具:电子负载、稳压电源、万用、电子温度计、数字电流表。 测试内容: 1、输出电流不断上升,输入电压不断下降的状态下,输出效率变化分布; 2、输入为恒压的状态下,不断的提高输出电流,输出效率的变化; 3、输出电流不断上升时,芯片发热温度 变化; 测试: 1 、控制输出电流从0.3A-1.9A 逐一递升变化，每0.1A，;稳压电源输出为4V,以实际电路输入电压为准,并读取电子负载上的显示参数，输出电压、电流，; 输入电压U0 输出电压 U1 电路板 输入电流 I0 输出电流 I1 2、控制输出电流从0.3A-1.9A,不断调整输入电压,使之为定值 ,并读取电子负载上的显示参数，输出电压、电流，; Recently completed clean energy reform, violations of the requirements will be banned. All of catering oil smoke purification measures must be installed, especially the outdoor barbecue, it is strictly prohibited to add barbecue stands, all existing business into the shop. (C) be sure to let the water cleaner. Water is the source of life, Foundation of ecological production. We 3、控制输出电流从0.3A-1.9A 逐一递升变化，每0.1A，;芯片等周围部件的温度变化; 测试数据: 1、输出电流不断上升,输入电压不断下降的状态下,输出效率变化分布; 2、恒压下的效率变化; , 输入3V恒压时,随电流的上升,转换效率的变化情况 Recently completed clean energy reform, violations of the requirements will be banned. All of catering oil smoke purification measures must be installed, especially the outdoor barbecue, it is strictly prohibited to add barbecue stands, all existing business into the shop.
