Other Parts Discussed in Thread: DLP3010, DLPC3433,
使用这个方案器件组合DLPC3433+DLPA2005+DLP3010,目前DLPA2005给DLP3010供电不正常,目前电压输出VOFS=4.3V,VBIAS=4.3V,VRST=0.4V,麻烦分析一下可能原因,谢谢!!

如果完全断开,VOFS和VBIAS完全没有电压。VRST电压0.2V.连接DLP3010,电压用示波器查看,VBIAS可以到18V和VOFX可以到10V,但是VRST只能到-5V,无法达到-10V,同时V6V这个管脚没有电压输出。麻烦再分析一下,谢谢!!
检查和更换D1.
1. DLPA2005损坏
2. 和DMD连接线不对或者DMD安装固定问题
