The LTC3891 and LTC7800 are pin compatible but have an upper output voltage limit of 24V, which I'd like to operate them at. The converters will supply a linear actuator that typically draws 8A continuous for about 15 seconds when lifting, then 2A continuous for about 15 seconds when lowering a load. The actuator does not move constantly but the converter needs to operate without forced air cooling at up to 50C ambient (estimate based on being semi-enclosed with 30Cish outside temps). Are there better options for this application that have similar cost/size? A single phase is probably more cost effective than a dual phase at these currents, but dual phase wouldn't be out of the question if there's a good part that I missed.
I did notice the LTC7891 might be an option because even though it is designed for use with GAN FETs it could be used with logic level MOSFETs. Any suggestions are appreciated.
