Two high-power adapters were compared on the same bench. The one using a resonant stage ran cooler at full load and produced a lower electromagnetic signature; the other met the same limits at a lower cost with a simpler control. …
An efficiency figure that beats the competition on the first page and disappears at half load is not a design advantage. Efficiency is a curve, and the useful specification states the points on that curve, the input voltage they were …
Two 65 W chargers were compared side by side: one GaN, one silicon, both meeting the same specification. The GaN unit was smaller and slightly more efficient at high line and full load; the silicon unit was cheaper by a …
Five items decide whether an extended range claim survives first contact with a customer: the voltage class of the construction, the marked cable in the box, the connector rating, the thermal result at the top of the range, and the …
A programme paid a premium for a GaN platform and then discovered that the enclosure had been sized for the higher frequency but not for the heat, so the design derated before it reached its rated output. The material had …
The most common specification error in this category is to state the wattage and assume the adjustable mode comes with it. The protocol support is an option, the range is a parameter, and the current limit is a third item. …
Two programmes adopted the extended power range in the same quarter. One shipped on schedule with a platform that was already characterised for the higher voltage; the other discovered that the cable, the connector and the thermal path all had …
Two chargers describe the same headline power and only one supports the adjustable range a phone uses to charge quickly. The two differ in the control loop, the firmware and the test plan, and the difference is invisible on a …
The cheapest way to protect a launch date is usually the one that costs nothing at the time: booking the slot earlier. The most expensive is the one taken in the final two weeks, when air freight and overtime are …
A brand placed its peak order in the same week as every other brand, and the goods arrived after the season had started. Nothing had gone wrong with the product or the factory: the order had joined the queue at …
A production schedule can be checked in four questions, and a schedule that answers all four is short. A schedule that answers none of them contains the same durations as the one beside it and no dates, which is why …
Two pilots ran in the same week on similar platforms. One produced a fixture change, a revised test limit and a verified packing process; the other produced photographs of some units and a request to proceed. Both were called pilots, …
