I have a few push pull SMSP's that output around 90VDC. I would like to leave them as is and add a buck to the transformer output. I am looking to do 48V 6A. I have used some calculators to provide me with the required component values but I do not know what controller to use. I would like to use a TI controller but I cannot find an application for a DC/DC buck that uses only an inductor and not a transformer. I am still new to most of this.
EDIT:
The supply also has a +-15 volt supply that is fed through some LM7815/LM7915 LDO regulators. The secondary tap is ~35V at the diodes.
This will allow me to use the primary push pull without any modification and have the required output that I need.
This is the controller I was looking at.
