RE-CIRCULATING DIODE
The LM3445 Buck converter requires a re-circulating diode D10 (see the Typical Application circuit to carry the
inductor current during the MOSFET Q2 off-time. The most efficient choice for D10 is a diode with a low forward
drop and near-zero reverse recovery time that can withstand a reverse voltage of the maximum voltage seen at
VBUCK. For a common 110VAC ± 20% line, the reverse voltage could be as high as 190V.

The current rating must be at least:
ID = 1 - (DMIN) x ILED(AVE)
