MOSFET Power supply

MOSFET Power supply

Our Reliable old linear supply design - literally thousands built - we still use two of these daily. Some nifty little circuit details -- the voltage reference, current sensing, boosted MOSFET gate supply, and plain simplicity - using a chip that now costs about 20p! A classic!

Note that the picture is of the later version which used a novel thyristor type pre-regulator. The design retained the same basic circuit blocks but was more complicated. It worked fine, but problems with the high peak-to-mean current ratios in the rectifier bridge could reduce reliability.
