WEBENCH® Tools: LM5141 driver was very weak ，IC was hot when input over 18V
Tool/software: WEBENCH® Design Tools
This is my second design LM5141,40V-5.2V DC-DC
I design the EVM refer to the WENBENCH tool schematic
When input is 40V，output is 5.V 3A，IC and MOS are very hot，about 100℃，
Here are there picture about the high and low MOS driver waves，in different output current。
Blue diagram is high MOS driver
Yellow diagram iS low MOS driver
output is1A
output is 2A
output is3A
See the above there picture，when operate the different output current ,the high MOSFET driver open time almost keep unchanged
Let us see the low MOS diver wave changes in different output current
1A
2A
3A
I am in interrogative ，as usual，when the loading is added，the high driver should gain the duty cycle in the buck circuit，Otherwise this state is not my hope, and why only the low driver duty cycle was added when the output current was added 1A to 3A?
I have test the high MOS Vgs，the wave was very strange
It was seen like not as full work，I gusset if it is the reason why MOSFET was very hot，even the output is only 1A
So my main question is something case the IC and MOSFET hot,I hope someone can help me to solve this problem?
I am sure that IC GND is enough，because the IC is not pover device
I found main reason was that high MOS driver is very weak when the input over 20V
like this pictures:
input is 12V,higt MOS Vgs is normal ，IC and MOS can't be hot
input is 30V,higt MOS Vgs wave is Disorderly，IC and MOS are hot
input is 40V,higt MOS Vgs wave is more in trouble
the driver is very weak，so that the MOS be hot when load 。this state I have been understand
But the IC be hot when input is higt voltage，and the driver wave can't serve MOS switch fully，
So what case the IC can't work in high input voltage？

TINA/Spice/UCC28C43: Simulation and model verification for UCC28C43
Part Number:UCC28C43
Tool/software:TINA-TI or Spice Models
A buck chopper is modelled in TINA software with UCC28C43. Power rating is 2.5kW. It has to operate from 65% duty to 96% duty @ 80 Hz. Model is successfully built to the requirements. Slope compensation parameters are calculated based on datasheet.
However, while testing the proto, results are not replicated to the simulation. We got sub-harmonic instability in the PWM output. We tried tuning every value of slope compensation parameters, didn't work. Current sensing is placed in switch path in beginning, now it changed to inductor path. Still, same result.
Output voltage voltage is regulated to the set value, throught the duty range, and response is smooth. No overshoots, no Undershoots.
I hope some of you can propose some clues/solution.
Thanks
Ravi

WEBENCH® Tools/TPS55340-Q1: Webench Board Layout problem
Part Number:TPS55340-Q1
Tool/software: WEBENCH® Design Tools
Hi
This is my first time working with Webench.
I created a design with the TPS55340-Q1 and would like to make a PC board but there are a few conflicts.
Looking at the WebTherm Simulations, D1 is incorrectly oriented on the board. Also the Board Layout from the cad file export
area is also incorrectly oriented and missing solder pads even if it would be rotated. In Cadsoft Eagle software the top placement layer
as well as the bottom placement layer have been removed so I am unable to alter the board myself.
I have not been successful in being able to talk directly to a TI support person. Does anyone know
of the path I should take to get this resolve so I can proceed with my project.
Thank you
Ralph

WEBENCH® Tools/LM5022: Boost Converter
Part Number:LM5022
Tool/software: WEBENCH® Design Tools
Hi, can anyone help me out in a design of boost converter. the input voltage is 12-13.5 volts as output is 180 volts maximum output current is 150mA here i have achieved those but the problem is mosfet. The mosfet i am using SIHB11N80E which is greater specs. the design recommends Vds 250 volts and current 3 Amps but it is having 850 and 8 amps respectively. The mosfet is getting too hot when boost converter is on load either load is low or high. Help me please thanks is advance.(Please visit the site to view this file)
