Hi Charles,
The LM5025C active clamp controller has hiccup mode of operation integrated into the device.
The external hiccup circuit for the UCC2897a has been tested and the complexity is required to provide safe operation of the UCC2897a in hiccup…
Hi Wangxin-san,
Thank you for last time.
I had a mistake.
Customer is using LM5025C.
Q1: Is your answer same even if customer uses LM5025C?
Q2: What is the defference of LM5025 and 5025C?
Best regards,
Shimizu
Other Parts Discussed in Thread: LM5025C Hi,
I'm using LM5025C ic to design 40W Power Supply with Active clamp forward converter topology.
Out Voltage 3.3V
Output current 12A
Input range 18-75V Dc.
Refered compensation network from the datasheet…
Hi Yoshi,
All TI Spice Models can be found at below link
https://webench.ti.com/webench5/spicemodels/?DCMP=hpa_hpa_elabs&HQS=spicerack#
LM5025 and LM5025C are similar parts for which we have TINA models.
Thanks & Regards,
Saket
Hi David,
Please refer to the following post. You will need the unencrypted model to import from one tool to another.
e2e.ti.com/.../3052.encrypted-models
Alternately, you can try using the LM5025C TINA-TI model as an alternate for your evaluation…
Thanks Garrett.........
I have one more query regarding LM5025C IC
Topology-Isolated, (Active clamp forward converter)
Input voltage- 18-75VDC
Output- 3.3V/12A
We used transistor based linear regulator for powering IC. Our input voltage is 18…
Dear Richard
Thank you for your quick reply.
Attached is simplified schematics of Active clamp, especially primary side.
Please refer to Fig 2.
Behavior of the UCC27200 when reached broken, VDD to GND is "short condition".

Kensuke-san,
Since my colleague Oliver is already verifying the answer to your other posts about LM5025A & LM5025B using the LM5025C EVM, we will be able to answer this question also.
We will post the replies when we have the verified results. This…
