Hey, I built a circuit as recommended in the datasheet, with R1 as pot to get variable output voltage. The problem I'm facing is I'm not getting load current more than 0.4A whereas the datasheet say it can output 5A. My output voltage drops if i increase…
The LT1072 Datasheet (page 9, attached) shows how to synchronize the device's switching to an external clock by using a BJT or FET from Vc to Gnd.
Can the LT1070 and/or LT1074 be synchronized using the same (or similar) technique?
我使用的是“MSE-16-EDP"的封装,好像是有点不太对(是AD自带的linear的库,有点坑啊),后面自己改了一下。另外,原理图如下,应该问题出在pin7上,对于LT8610A,这个脚应该浮空,不用接地,因为接地后就导致与输入24V过于接近。所以我后面的封装这个pin7引脚没有画上,增大24V对地空隙,是否可行?谢谢了!
图一:参考原理图,输入EMI网络是三路共用,通过网络之后分别到三路电源的输入端,这是其中一路。
图二:准备使用的封装,其中pin7已被移除
图三:LT8610A的封装对比…
