Q
I am looking for a Half-Bridge DC/DC Controller for medical application. DC
input is +360V, output +36V/10A. Isolation transformer should meet medical
double insulation reguirements. Could you help me with this?

We really do not have a dedicated analog Half bridge controller. ADP1621 could
work if external drivers and some timing logic was used, but it really is not
optimized for the task. We do however have solutions with our digital ADP1046.
It can control half bridge full bridge and many other topologies. Programming
of the device can easily be done via a graphical user interface. Please check
the the link to the product page:

This solution comes with many nice features such as power monitoring,
adjustable flag settings, a fully digital control loop and much more. No
programming knowledge necessary. Just the setting of a few registers with the
GUI. It can be downloaded for free from the ADP1046 product page. Checking out
the GUI helps to understand what the ADP1046 can and cannot do.
You probably get the 360V from a PFC stage. If so, we also have a very nice PFC
solution with our ADP1047 :
