 We use the IC for SEPIC for inverter‘s resolver‘s power， when the temp=-20℃ on vehicle ，at the start time,the fault UV occur ，the sepic output can't output voltage。

But when other High and low temperature testing，the…

输入电压为5V，希望输出电压为3-15V，输出电流最大1A，并且可以通过程序控制输出电压，希望外围电路越简单越好，不知道有没有推荐的电源芯片?

LM3481的datasheet上 boost参考电路是通过FB引脚上的电阻RF1和RF2来设置输出电压，有没有电路可以通过外部电压给定控制输出电压，实现输出电压可调。如果LM3481没有这种功能，请帮忙推荐一款通过外部电压控制输出电压的boost控制芯片。

I use a flyback with 4 outputs to supply 6 IGBT pre-driver in a PMSM ECU. Normally my power board is OK. But I met a abnormal phenomenon in one board. 

The flyback is with 12V input and 4 lanes of 15V output. When power on with 12V…

LM3481有个问题帮忙确认下，输入14V，输出20V，输出电流10mA，开始启动时，最小占空比持续几个周期关闭一段时间再持续几个周期关断（期间输出电压振荡），一段时间直到可以稳定在最小占空比运行（输出电压出现一个平台），输出电压开始继续上升，输出电压开始启动时的振荡和占空比的跳周期情况是否是正常现象，是否芯片设计的机制就是这样？目前担心是否会存在某种工况抑制卡在这个振荡的…

已经有实物反激电路，输入电压5V，输出200V，想进行仿真，但是始终有问题，仿真输出电压为负数，请问TI的工作人员能否帮忙进行仿真文件的修改，谢谢啦（变压器变比为10.5：1）LM3481 FLYBACK.TSC
