| A niche chip (LT4320) for mains powered AC -> low volt DC "linear" based psu ? |

Not sure if this is old news, just found out that this little gem should be one of the nice component to replace those scorching hot silicon rectifier. For sure if I'm going to build another linear based power supply (one off project), this will be in my shopping list. Also I'm curious, if the input is pure DC, isn't this chip will act like an overkill reverse polarity protection circuit ? ??? Any second thought ?

Not a bad device, solves the problem in a very elegant way. |

I saw this one a few weeks ago and thought it was a brilliant idea. I mean who doesn't like the thought of extremely low losses for rectification? The only thing that made me sad is the fact that you need to use external MOSFETs with it. Give me a drop in replacement option for current SIL bridge rectifiers, and I will LOVE it. -kizzap |
