This picture is a 15 ~ 58VIN to 33.3V 3A LED automotive headlamp driver circuit diagram, its efficiency is as high as 98.5%.

Aircraft and large trucks with 24V batteries require powerful, efficient, and rugged headlights and reflectors. This circuit shows a 33.3V, 3A (9 Luminus SSR-90 LED) buck-boost LED driver, which operates on 15V to 58V input and can achieve efficiencies as high as 98.5%. The four-switch synchronous topology can drive high-power LEDs and produce very little switching power loss (and minimal temperature rise).
