11 Practical Aluminum Wire Gauge Amperage Chart Images - [18] the burnt charger is an apple a1222 85w macbook charger, that's a different version from the a1172 charger within the relaxation of the teardown. The a1222 is in a barely smaller, rectangular case and has a very different layout based at the ncp 1203 pwm controller chip. Components within the a1222 charger are packed even greater tightly than inside the a1172 charger. Primarily based at the burnt-up charger, i think they driven the density a chunk too a long way.

First-rate teardown. I'm within the technique of assembling & constructing my own very clean (fine/filtered) electricity deliver for my mobile necessities (going direct dc to dc) and was thinking a natural 20v turned into all that turned into needed. Pass discern this is a little extra complicated. The board & chip i'll be the usage of is certainly green (expected ninety five-99 constantly) and so need to no longer waste energy when the modern draw is low (say whilst my 15" mbp is completely charged), but that also assumes the mbp gained't waste the 20v supplied and simply draw greater modern because it can? Does everyone have the solution to that? Need to it without a doubt drop the voltage a few so good judgment inside the mbp does now not waste strength? Ken, the separation among high and coffee power sections isn't distinct enough here for me to recognize the solution, but in your arms on revel in with dissecting this or any apple charger and based of your one comment above, do you suspect it viable to cleanly upload a tap into the low energy component (pass the transformer system) and deliver a base/smooth dc voltage to the board? My desire is to repurpose my cutting-edge or perhaps an older 85w charger and to replicate precisely what apple does through the usage of all their common sense after the fundamental ad-dc transformer degree, and now not simply the connector. Has all of us you know of done this?.

The maximum essential function of the secondary is to hold the damaging excessive voltages within the relaxation of the charger away from the output, to keep away from potentially fatal shocks. The isolation boundary marked in crimson on the sooner diagram shows the separation among the high-voltage primary and the low-voltage secondary. The 2 facets are separated by a distance of about 6 mm, and only special components can go this boundary.
