Is there a reference design about digital peak current mode control or bang bang charge control for LLC resonant converter by MCF56F83xxx or MC56F81xxx to implement those?
Digital LLC converter of peak current mode control concept is similar to FAN7688 or NCP1399 analog controller IC.
Digital LLC converter of bang bang charge control concept is similar to TEA2016 controller IC.
Could anyone provide me related docs and source code?
I do not know if you use LLC resonant converter layout or general Buck layout with peak current mode control.
If you use LLC resonant converter, pls refer to the link:
The LLC varies PWM frequency to adjust the output voltage, it does not use peak current control mode. I suppose that peak current control mode is used in current loop with fixed PWM frequency.
I once received a similar solution on this webinar.

Could the nxp provide related documents and source code?
Hi xiangiun rong
Thanks your reply.
I think that the LLC converter also can implement peak current mode control(Charge current mode control).
Our layout get the resonant current and integrate it and it will into internal comparator.
When occurs peak current event, It is going to turn off PWM and then we also want to get toff time as some as ton time but we don't know how to implement it.
You can refer as follow. We want to implement below docs method by full digital control via DSC.
From your Email, it appears you are student in a university. The source code is confidential, the product manager is responsible for the distributing the source code and schematics based on business.
You said that you was invited to attend a DSC training by AE, can you contact him to get the source code and schematics?
It is dependent on the business whether the product manager would like to share the solution with you or not. If you want to request the solution, you have to submit your company name, address, country, tel number,project, part number, estimated pcs so that the product manager and FAE can evaluate.
