Want to design DCDC converter using L6424A IC

[Nayeem]

Hi,

 

I want to design a 600 W converter which should work during power shut down 190 V to 60 V input and output voltage will be 300 V. Switching frequency 150 kHz to 190 kHz. Want to use L6462A IC as there is a evel board which perform the same (ACDC  -- PN: EVL6462A-250W-M). 

Operation time = 100 msec.

I also need an enable signal to turn on the DCDC converter.

Please let me help to design the schematic and are we able to use L6462A IC for the application.

 

Additional Information:

1. Topology is already selected and simulation is done. --- Non isolated boost converter.
2. L6462A is ok to use? ST already build an eval board as PFC. Can anyone provide me the schematics or suggestion for the DCDC converter.
3. Peak current controller is fine.
4. I also want to mention that we already build the dcdc converter with TI28379D microcontroller. Reason to use the IC (L6462A or else) because we want to bypass the software coding.
