Electronics engineer - DC-DC buck boost functionality

Job ID: 33035755

Budget: $30 – $250 AUD

We have a board (24vin) that has a step up function (50v) and two step down functions (12v, 5v). Need help selecting components for the step up and step down as we currently use expensive modules that are not entirely suitable. Note we are not looking to use ebay modules for these functions. Ideally we are looking for an engineer who will use components for the buck / boost functions.

Current draw is very low. The boost is only on for a very short time and needs a current limiting mosfet circuit. The 12v and 5v lines are 0.5A max. The 5v line is usually off also, so a linear regulator would work here.

Keen to find an engineer who can provide schematics, BOM, layout. Also looking for someone who will care about our project and offer some ideas rather than just doing what I ask. Very keen to have an ongoing relationship with future work.

Prefer to work fixed price, so if there is more info you need to provide a fixed quote, please ask.
