Dear Stephen,

I have raised a ticket. In the meantime can you please share a copy of the detailed design guide.
The design guide will expedite our process of completing the design.

Regards,
Harish

Hi Harish,

Just to clarify, what information are you looking for in the design guide? I have attached a few resources that should assist your design. Please reference the following links. First link will help define the values for the resonant tank according to your design specifications. The second is an article outlining our Programmable Power Manager for the 121x series. The third link will take you to our resources page focused on PFC/LLC designs, where there are also some reference designs.

Hope this helps.

Dear Stephen,

I don’t understand a simple aspect. You(MPS) have manufactured an IC HR1213 why can’t you have one straightforward design tool or a guide that will help us calculate the component values based on input and output? Your resonant tank tool does not work for our input/output values.

Our AC input is 190-265 RMS ( 50 Hz) and output is 210V (DC) and output current 3-4 Amps.
Let me know where I can find some guide to help me choose the component values( all) and come up with inductors and transformer design.
We want to follow "Typical Application Circuit (VCC Supplied by Auxiliary Winding) " as per your data sheet

Hello Harish,

I understand your frustration. Unfortunately, we are unable to share some of that information due to NDA restrictions and proprietary information surrounding this product. Since you have already submitted a ticket and are in our system, the assigned FAE to you will be able to assist you further in the design and development of this product.

Dear Stephen,

Well this is strange. I am asking for the mathematical equations to calculate component values. Let me know if you want me to sign your NDA. I will do it.
Who is our design FAE? We need to move very quickly please.

Regards,
Harish

Will you guys respond or we will drop your device ? we will not continue with our design.
If we don’t hear from you we will drop it please.

Hello Harish,

We are currently investigating your ticket. I will check in internally to get the NDA and design tools to you.
