SPICE model for LDFPVR ?

[MUTHUKUMAR]

Your products have been instrumental in helping us achieve remarkable advancements, and we truly appreciate the quality and support you provide.

 

I am currently developing VHF PA  circuit that incorporates your product, the LDFPVR . To validate the design concept and ensure accurate simulation results, I kindly request the SPICE model for this component.

 

I have access to ANSYS HFSS and other simulation tools, and this project is of high priority. Your support in providing the model at your earliest convenience would be greatly appreciated.

 

 

Note : If your team is not related to the technical aspects of the SPICE model, could you please forward this request to the relevant technical team? I am able to reach out to you from my side, but I need assistance in connecting with the appropriate team..

Over 48 hours have passed since our request for the LDFPVR Spice model. This is critical to our simulation, and the delay is affecting our timeline.

Please prioritize and share the model as soon as possible.

You have already created a ticket # 00236494 at the Online Support OLS, where the issue is currently being processed. I ask for your understanding and a little patience, further urging in the community will have no accelerating effect.

As of June 23, 2025, 10:16 AM, approximately 84 hours have passed since our request for the LDFPVR Spice model. This delay is critical and is impacting our simulation timeline.

The LDFPVR voltage regulator is a core component for many engineering applications. It is unacceptable that the SPICE model and essential documentation are missing from your official product page.

As a manufacturer, it is your responsibility to ensure that all simulation models and technical resources are readily available to support customer integration. Without these, implementation in real-world projects is hindered, causing delays and inefficiencies.

We demand that you upload the complete set of product-related documents, including the SPICE model, to your sales and support portals immediately. Please clarify how customers are expected to simulate and validate your products in the absence of these resources.

I’m extremely disappointed with the lack of support regarding the SPICE model request. Despite repeated follow-ups over the past 7 days and 48 hours, there has been no meaningful response.

This delay has seriously impacted our development timelines and eroded trust in your products. It’s unacceptable that a released product’s SPICE model is still unavailable, raising concerns about the viability of your power electronics portfolio.

If this issue isn’t resolved immediately, I will escalate further and share this experience publicly to warn other customers.

[MUTHUKUMAR]

Please provide an urgent update on your team’s progress. It’s been 14 days, and the technical issue remains unresolved. A customer is awaiting clarity, and I need to understand why this is still pending.

If your team cannot deliver timely solutions, we need to reassess roles and responsibilities. Continued delays are impacting critical deliveries and customer trust.

Dear Super Wow OLS Support Team,

 

Thank you for your support over the past two weeks. Despite your efforts, the results did not meet our expectations. As a result, our company has decided to discontinue the use of your products across all current and future projects.

 

Please proceed with closing the support ticket. We wish your team success in future endeavors and hope this feedback contributes to your continued improvement.

 

"Please take this as sincere feedback: your team is currently not meeting the expectations required for this role. If you value accountability and professionalism, I would expect an apology."

Merged threads for the same question.

Hi Andrew Neil

I have always trusted your expertise and support. You are among the top solution providers, which is why I reached out to you on June 17 regarding the LDFPVR Spice model and requested that a case be opened.

However, it has now been over 20 days, and I have not received a single response. I am unsure of your case handling procedure, and this delay has caused significant concern. While Peter advised me to be patient, I must express that I have already waited patiently for nearly three weeks.

Unfortunately, due to the lack of response and the unavailability of the Spice model, our $1 million project was canceled by the end customer—resulting in a major loss for our organization.

You really should take this up with your local sales office, and FAE responsible for your account.

Andrew is just a User/Moderator, and has no responsibility for your account, nor pending OLS request.

There's a lot of berating going on in that thread, and whilst that might work in your part of the internets, it's not at all productive on user forums
