Semiconductors lose their ability to deliver current (and thus power) with temperature, a phenomenon called deranging.

Deranging or De-rating?

When I hear deranging, I think of something as being deranged.

ooops. Thanks for correcting me. Fixed!

Just to let you guys know that I "upgraded" this article to a full review, adding results of our load tests.

Enjoy!

Thanks,

The +12 V output is produced by two STPS60L45CW Schottky rectifiers connected in parallel, which can deliver up to 60 A each (30 A per internal diode, measured at 135º C). The maximum theoretical current the +12 V line can deliver is given by the formula I / (1 - D) where D is the duty cycle used and I is the maximum current supported by the rectifying diode (which in this case is made by two 30 A diodes in parallel). Just as an exercise, we can assume a typical duty cycle of 30%. This would give us a maximum theoretical current of 114 A or 1,371 W for the +12 V output. The maximum current this line can really deliver will depend on other components, in particular the coil used. As you can see this section is highly overspec'ed.

60amps / .7=86 amps.
