LT3922 Buck Mode Schematic

Hi,

The schematic for a buck mode LED driver written in LT3922 datasheet page 27 seems not correct.

I tried this schematic on LTspice but I could not get correct data. LT3922 seems not to work since VIN=VSW and ILED=0A.

If it is not correct, please send your recommended schematic for a buck mode.

Thanks,

Kazu
