TPS7A33: We need a negative buck converter for -24V to -16V as a pre-regulator for negative LDOs.

Part Number: TPS7A33
Other Parts Discussed in Thread: TPS7A47, LMZ14201H, TPS40210, PMP9624, PMP, TPS563249, TPS563240, TPS56339I have similar questions related to this post "TPS7A33: Which negative to negative buck as pre-regulator". We have an industry power source that is the power input to our PCB, which is +24V, GND, -24V. We want to generate positive and negative (clean, low noise, high PSRR) powers of +15V, GND, -15V, using TPS7A33 and TPS7A47. A DCDC pre-regulator is needed for optimum thermal designs using LDO. We have chosen an appropriate power module, lmz14201h, for converting +24V downto +16V. And now I want to find the best DCDC that can be used to convert -24V to -16V. Note that, we do not need to generate -16V from +24V. Is there any power module or design notes from TI that can be used to down-convert -24V to -16V? Thanks in advance, and we are looking forward to your replies.
