Hi Lawrence,
I recommned increasing the boot cap to 100nF and using only one FET in the high-side and low-side positions (no need for 2 in parallel as the output current is only 2A). Also, it's good to install a ceramic output cap to conduct the switching…
Part Number: LM5146 Tool/software: Hi, I'm having trouble getting an LM5146 circuit to work as I want. My setup has Vin=100V and Vout=52V, SYNCIN pulled high, and no load during power-up. About N ms after the output reaches the target voltage, switching…
Part Number: LM5145-Q1 Other Parts Discussed in Thread: CSD19534Q5A According to last question, I finally choose CSD19534Q5A for high side and FDMS86101 for lower side (with lower Res(on))
Could you please review the following design in attachment please…
Hello, I keep getting "file type is not allowed" for the .xlsm extension. I have renamed it to .xls for the upload. LM5146-LV5144_quickstart_calculator_revB1_09-05-2024.xls Also attached are the SW & low side gate waveforms (with the original PCB configuration…
Hello
At this time we do not have an averaged model available for this device.
The best plan is to follow the guidance in the app note that I have attached here
to help with your input filter design. By using a damping capacitor in your filter,…
Part Number: LM5146DESIGN-CALC Other Parts Discussed in Thread: LM5146 Hi team,
my customer was seeing a spike in temperature of the device so we had recommended they change the Fsw.
they reduced it to 120kHz which helped. however, now they have…
Hello Yumiko,
There are various ways to filter input and output noise. I've attached a few Application Reports in which I believe can be helpful information. Also, please take a look at the previous post ( link ) which is similar to your question. …
Unfortunately, I do not have an exact recommendation. Selecting the correct Ferrite Bead filter varies through applications. But, below I have provided some technical documentations in which I believe can be very helpful if you are planning on implementing…
Part Number: LM5145 Other Parts Discussed in Thread: TPS40170 , LM5146 Hi Team
客戶目前使用LM5145RGYR!
客戶目前LM5145 的用法如下圖， 做電池應用的CC/CV控制。
其將TPS40170改為LM5145, 其餘線路follow 應用線路，請幫忙確認LM5145是否可這樣應用，謝謝。
客戶產品規格為: 48-60Vin , 20-42Vo /10A , 輸出電壓屆時會由MCU介入調正OPA…
