Our customer is starting a design shortly for new Chassis for monitoring flight
data in commercial aircraft. The power supply is being looked at. They are
considering LTC solution....LT8705. They like this and are keen to learn if we
have anything close to this in performance. Vin can vary from +18V up to +40V.


We do not have any 4-switch buck-boost controllers. We have the IP for
integrated once but not covering these high voltages.

This is definitely a unique LTC solution, I am not sure any other suppliers
have such controllers.

We could support it with some non-isolated type of fly-back topology similar to
the attached schematics using the ADP185x, Vin and Vout can be anything as long
as you have a 5V bias for the IC.
