Power supply to PCB from ~600V system

Ole Marius Forbord

Hello,

As a (little) part of our Formula Student project my team and I need to supply 1 PCB from the HV system in the car (rated at 588V). The PCB has an input of 24V @150mA. Any ideas of how to solve this?

Best regards,

Hello Ole,
In TI DESIGNS area on the web, you can search for Power Designs, and filter by VINmax.
www.ti.com/.../refdesignsearchresults.tsp

Search power designs by parameters

A top down filter for Vin(V) (max) yields several approaches.
The first one looks good.
700V-860V input to 16.5V@0.5A output

Here is another but isolated;
400-V to 690-V AC Input, 50-W Flyback Isolated Power Supply Reference Design for Motor Drives

These are design examples, NOT PURCHASABLE hardware.
How do these look?
