non isolated dcdc 16-75Vin - 15Vout @1A

Other Parts Discussed in Thread: LM5164, LM5088, LM5161

Hi,

My customer is defining the design of a gps to be installed on a ship.

Currently the need would be:

Solution not isolated
Operative input voltage: 18-56V (48V nominal)
Maximum input voltage: 16 (or less if the step down solution is not used) -75V (or greater)
Output voltage: 15V
Output Current: 1A
Max Ambient temperature: 70 ° C

I found the solutions:
• LM5164 (possibly the Q1 version)
• LM5088 (possibly the Q1 version)

Is there anything else that can be evaluated?

Many Thanks,

Antonio
