Hello,
We need to design the following Buck-boost converter for 650W.
Vin = 18 to 32V
Vout = 5 to 34V
Output power = 650W
Do you know of any PWM controllers on the market which can implement this?
I believe that a synchronous boost controller could do the job?
I believe that we will need to implement isolated high side bias supplies to power the upper fet gate drivers.
Also, do you believe that the current sense transformer primary should be placed upstream of the most "upstream" fet (ie upstream of M4 or M8)?
