Hello!We have a LTC3115-2 that has a nominal 28V input and a nominal 28V output. It should be noted that we are trying to power the converter into a 750uF output capacitance (the 9ms soft start time is nowhere near enough). For a while, we saw no issue…
您好，我使用LTspice XVII对LTC3115-2进行电路仿真，采用数据手册中推荐的参考电路方案，但仿出来的波形很奇怪，不知道问题出在哪里，请给予帮助和解答。谢谢！
Hi,
The applications information section of the LTC3115-2 datasheet references use of a Bode plot generated in LTspice from the small signal parameters of the LTC3115-2. Is the LTspice model available for customer use when calculating compensation loop…
在使用LTC3115-1过程中，PWM/SYNC这个引脚老是烧掉，与地导通，同时输出电压为零。外围电路是根据datasheet上的电路进行设计的，请问是什么原因导致的呢？
In the process of using LTC3115-1, the PWM/SYNC pin is always burned, connecting to ground of the system, and the output voltage is zero. The peripheral circuit is…
Dears,
We are designing one boost DC, with 3.6-7.2v battery input, we wish to get 13.8v/1A output. Preliminary we choose LTC3115-1
From the datasheet, we set the Rtop=3.2M and Rbot=249k, F=1M, L=47uH etc...but we can not find exactly discription about…
Hi
I'm a DFAE in Japan. Our customer evaluates LTC3115-1 and faces similar to hiccup mode (Vo is up and down) when Vin=4V, Vo=12V and IO>200mA. The power supply design spec is Vin=4V~32V, Vo=12V and Io=300mA. It seems that the load current that…
Hello,
A couple of questions about the LTC3115-1, after noting that oscillations occur on either side of the switch depending on buck vs. boost mode:
I want to make a variable power supply controlled by a microcontroller (stm32f767zi).
The input voltage will be 24V. The output voltage should be adjustable (via the microcontroller) between 14V and 31V.
The output current is maximum 0.8A.
Can…
