VIN=12V@33A, Output ±16V@20A, ±6V@20A, +5V@20A in our system(100x50mm layout area)
We choose LTC7815 for +16V,+6V,+5V, and LT3840 for -16V, -6V. SWfreq=2MHz.
1. Could you help to double check the P/Ns and give us some advice.
2. if This desgin is ok, please help to provide DC2738A-2.asc files（LT spice can not find LTC7815 sim）.
Thank you very much.

Hi dkb,
two questions about LT3840,
1. Vin =12V, LT spice didn't work.(Now use 24Vin, Cap loading from 20uF-680uF as application notes)
2. Vout Ringing(with no Res loading)
attached test bench pic and asc files for debugging. Thank you very much.
