LED Boost converter efficiency improvement

<< < (3/3)

TmaxElectronics:
OK so a quick update:

i have changed the inductor to a 11.2uH one (just two of the old ones in series) and reduced the switching frequency to ~150kHz.
That improved efficiency to ~ 87% at 150W and ~85% at 210W (max LED power) with 25V input, making my circuit dissipate 10W less ;D

However there is still the same waveform on the NFet (which might be correct after all), and it still switches off the PFet for around 300ns every cycle, not sure if that is really an issue though.

At this time i can live with the efficiency (and the mosfets too ;) ) so thanks for the help everyone (more tips are of course appreciated).

right now i can run the lamp with 10A converter input current limit (not actually limiting at 25V in), with the inductor getting to 75°, the bottom side mosfet at 89° (right on the tab) and the LED at 74° (C, of course :P ). and if i improve the thermal resistance between the PCB and the heatsink, I think I can improve those temps a little more
