Planar trafo and InnoSwitch4
Hi!
I need to design a flat power supply (max 10 mm) 60W/24V. The maximum load will not be permanent. just for a few seconds.
I started the design based on the RDR-928 with the idea of just modifying the transformer.
But I gave up on the wound transformer due to non-communication from both the core manufacturer (Hwahe), and the bobbin manufacturer (TBI). These are the only manufacturers where I found a core and bobbin with the required parameters.
Yesterday an email popped up on me that PI-Expert can do planar transformers.
I found a good example (DER-626), but it is only semi-planar.
Obviously, the E32/6/20/R-3C95 core is capable of transferring such power and is made by several reliable manufacturers.
I wanted to use InnoSwitch4, but it doesn't support planar transformers.
I would like to know if this support will eventually be added?
Thank you.
Hi,
Thank you for the interest in PI products.
InnoSwitch 4 will be updated to planar magnetic support, unfortunately I cannot give you a date.
In the meantime, you can still use InnoSwitch 4 platform for your design, adjusting the parameters to suit planar design (like number of turns). Then use InnoSwitch 3 platform with similar design to reach the required planar transformer. The E32 core is already in the database.
It is not a convenient solution, but it will do the job.
Best Regards,
