TPS61170: Phantom power application circuit

Part Number: TPS61170
Other Parts Discussed in Thread: TPS61175, LM5001

Hi sir,

I am puzzled on 48v phantom power circuit.

I found in this product's datasheet a schematic to boost up to 48V for phantom power. I'm a little confused though because it lists a maximum output voltage of 38V. I tried to create the schematic in webench but it again wouldn't let me use a voltage higher than 38. The schematic appears to have additional capacitors and diodes than a typical boost topology.

Could you explain how those are used to achieve a voltage higher than the listed maximum output voltage?

Also, do you have any other DC-DC converters you would recommend for phantom power applications?

Thank you.
