TPS54335A: Could you tell me about "Using TPS54335A's Flyback circuit"?

Hi, team.

My customers are looking for devices under the following specifications,

I have proposed at LM5160A and TI-design (www.tij.co.jp/.../PMP10532

<Specification>

Input：DC 23 to 25.5 V

Output：DC 5.25 V ± 5% (DC 5 V to 5.5 V) / 500 mA @ max

APLI：INVERTER
DEM：10 k / Month
Mass Pro Target：about 2020 year

However, the customer need packages with feet, and we fight with the six competitor companies,

and since we are proposing devices with ROHM of about $1.0,

we are trying to proposal with TPS54335A by Flyback.

So question.

① Can I use Flyback circuit with TPS54335A?

② In case of "Yes", can you create a circuit diagram that meets the above specifications?

(At first, It's OK even from simple circuit diagram)

Could help me?

Best regards,
