LMZM33604: Question about IBB topology by using buck module

Hello team,

I'd like to propose TI solution to the customer for below condition. I reviewed Apps note SNVA856A(https://www.ti.com/lit/pdf/snva856?keyMatch=WORKING%20WITH%20IBB). Can you check LMZM33604 could be one of solution? And also, please recommend more suitable modules? Buck converters are also okay. 

• Vin : 5V to 10V
• Vout : -20V. to -25V
• Iout : 0.7A is enough

Best Regards,

Austin
