    Hi Yamaguchi-san, Sorry for my misunderstanding. TI has many MOSFET package options including 2x2mm, 3x3mm & 5x6 SON and D2PAK. that can dissipate greater power than the Toshiba device. I did a search for FETs in these packages rated 30V to 60V and…

    Siyu, I think the toggle flip-flop in the block diagram on page one of the spec should have let you know that the max you will get with this device is 50% duty. Go to page 43 and 44 of the attached and select a more suitable part.
