Part Number: LM51231-Q1 Other Parts Discussed in Thread: LM5122 Tool/software: Hi TI Team,
I am currently working on a boost converter design using the LM51231-Q1 with the following specifications:
Input Voltage: 12V
Output Voltage: 36V…
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…
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…
Part Number: LM5146-Q1 Other Parts Discussed in Thread: LM70860 Tool/software: Thank you, Tim. I have checked the quick start calculator and have attached the Excel sheet for your review. Please let me know if any changes are needed. Untitled spreadsheet…
Thank you, Timothy.
We think it is the loop compensation issue. We used the design in below quickstart calculator, and the issue of startup was solved. However, in the Bode Plot, you can see the loop bandwidth is very narrow, and the slope is -40db…
Hi Niklas,
Thanks for schematic validation, but can you please confirm if you changed the switching frequency to 2.2 MHz ? By default it comes up at 440KHz.
I calculated again using the quick-start tool and changed the compensation network accordingly…
Part Number: UC2842 Other Parts Discussed in Thread: UC2706 Dear team,
I am designing a push-Pull converter using UC2842 and UC2706 with reference to U-101 200KHz Current-Mode Converter provides 500W.
Can I get the simulation model for the power supply…

I reviewed the information and entered the schematic values into an excel sheet (attached) to check the loop stability.
I get a crossover frequency of 85kHz and a phase margin of ~40 degrees. The goal would be to have…
Other Parts Discussed in Thread: LM27403 I've got a power supply design, designed almost entirely using Webbench. The DC input voltage is between 15 and 20V, and I need to generate a variety of voltages for my circuit. Webbench proposed stepping the incoming…
Hi Jijesh Janardhanan ,
I filled the Excel calculator with your design conditions and actual output capacitance (3*22uF + 18*10uF) and have attached it here. The compensation component values under Step 7 are quite different from what you currently…
