Viper16降压非隔离电压低于预期

我遵循了Viper16设计工具并遵循了推荐的组件。结果是电压低于预期(预期5v时为4.5v)和电压下降,电流从5mA下降到50mA降至4.2v。看看引脚1,2 GND的FB输入,它仍然保持在3.3V ....那么为什么输出会下降呢?有没有人有Viper16工作?

I have followed the Viper16 design tool and have followed the recommended components. The result is a voltage that is lower than expected (4.5v when expecting 5v) and dropping voltage as current increased from 5mA to 50mA drops to 4.2v. Looking at the FB input referenced to pin 1,2 GND it remains at 3.3v .... so why does the output drop? Has anyone got a Viper16 to work?

克里斯,
 
我的设计与Viper26有类似的问题。你找到了解决方案吗?
应用支持很慢,不存在。我对你如何解决这个问题很感兴趣。

Chris,

I have a similar issue with my design with a Viper26.  Have you found a solution?
Apps support is slow to non-existent. I am interested as to how you solve this problem.
