Hello, the following is a 40W boost converter with latch-OFF short circuit protection.
The short circuit protection is needed because as you know, the boost converter lacks intrinsic short circuit protection unlike the Flyback, Sepic and buckboost converter.
Would this be an acceptable solution as an Automotive power supply to supply a Daytime running light on a car?

The boost converter has..
Vin=10V
Vout = 48V
Power output = just over 40W.
The load is several Buck LED drivers.
F(sw) = 138KHz.

schematic and LTspice simulation is attached.
