I removed C111 and C112 and tested again. I did not notice any change. The 49.9R resistors are placed close to the device.
Here is the schematic CES 391-1 D-2-6.pdf
Hi Ryuuichi,
The 5V models have been updated to reflect the negative voltage fix.
See the models in the link below:
Make sure the models are the ones updated in 2018.

Tanks JCHK,
I got the reference design of LM5045, please refer the attached file.
Please help to check it, could I use LM5046 to replace it directly.
if there is change other component, please let me know.

Hello again. I continue with snva627b.pdf . I have a question. I am trying to determinate the formula in below
For this example
Rslope = 1K
Vout = 60V
Rcs = 3R
Lfilter = 4uH/2 = 2uH
Fosc = 416666 Hz
Islope = 100uA
When I wrote these…
Hello,
thank you for prompt answer. I have bought 2 EVMs to test current capability and I conected them in parallel. When I tested them everything worked fine, but It was few months ago. I did my revision and now I am testing it and I found this problem…
Hi Jerry
Thank you for your feedback!
One more question, c urrently client use LM5039, if client want to refer to Secondary Side Soft-Start of LM5027 (attached spec p8~p10 as shown below)
Does the Secondary Side Soft-Start SCH apply to LM5039? THX…
Part Number: BQ24253 Other Parts Discussed in Thread: BQ24266 , LMR14030 , BQ25606 Dear Sir/Madam,
We were using BQ24266 in our circuit, as it is NRND we have replaced the BQ24266 circuit using BQ24253. Attaching the schematic for the battery charger…
It is in the 19th page of this pdf under the title "2.2.3 Isolated Voltage Measurement Using AMC1200"
I plan to use the charger for the High side power.

Hello Nicholas,
Converting a -Vin negative voltage to a -Vout lesser negative voltage is fairly easy as the topology goes. A buck or synchronous buck will work fine. The problem is sensing the negative output voltage. Since the IC and converter circuit…
