Part Number: LM5118 SPEC:
Vin:20-60V Vout: 33V 2A
Actual measurement:
Vin:38-60V, Output is normal
Vin: 20-38V, the output voltage cannot stably output 33V.
I put the customer's schematic in the attachment.
Thank you for finding out the reason…

Hello,
I'm simulating the buck-boost converter reference design found in TIDA-01179 , however the simulation fails with various convergence problems:

Hi Najma,
your calculation looks OK.
For reduction of the loss you can have a lower voltage at VCCX - still higher then 7V to get enough gate signal
e.g. with 10V it would be:
LDO power dissipation = (VCCX-VCC)*{(Qg*fsw)+IBAIS} = (10-7) * ((96nC*221000…
Part Number: LM5118 Hello.
We are working on a webench design LM5118MH design and are having issues getting the switcher to run. It is 12V - 30VDC in to 24V @ 3A output without any changes except some higher voltage values on caps. The switcher is holding…
Part Number: LM5118 Hi,
Vin(min) - 9V
Vin(max) - 69V
Vout - 12V
Iout - 3A
For the Enable signal, we are planning to use a GPIO from controller to toggle the pin. In datasheet it has been mentioned that, Enable pin status as per the voltage across the…

Part Number: LM5118-Q1 Other Parts Discussed in Thread: LM70880 , , LM5177 Hi TEAM
Our customers want the boards we develop to work well in 12V, 24V, and 48V vehicle battery environments.
At first, I tried to use a buck boost product (LM70880), but considering…
Part Number: LM5118 Hello,
I am designing a converter with LM5118. In this process, I follow the typical application in the datasheet. However, I noticed some errors in the calculations and I would like to both report and confirm them.
The first error…
