Hello,
We our trying to design a boost converter.
Specification
Vin min - 40V Vin max - 56V.
Vout - 72V.
Iout - 3.5A.
Based on our requirements we used TI webench for designing.
We designed the circuit & PCB as suggested by Webench. But the problem is the output voltage is same as that of input voltage. For e.g. @48V of input supply the output is also 48V.
I am attaching the Webench design & our circuit schematic https://drive.google.com/file/d/12G2P0QTnLjonFxk91GwlJD6__s3S946Z/view?usp=sharing
