The order book tells a different story from the specification sheets. Buyers are asking for smaller enclosures at the same output, a second port as standard, and thermal evidence before the sample rather than after it.
This guide is part of our GaN Charger Technology. Read the full topic guide for the decisions that come before and after this step.
GaN charger trends: five requests in the order book
Smaller enclosures, a second port, higher tiers, thermal evidence earlier and a second qualified device.
Each request has moved from occasional to routine over a period, and each changes something in the programme: the enclosure, the port layout, the switching stage, the test plan or the approved component list.
Trend 1: smaller at the same output
The request that drives the switching frequency.
Buyers ask for the same wattage in a smaller body, which is the request that leads to a higher switching frequency, smaller magnetics and a tighter thermal path. The enclosure becomes the design input rather than the output.
Trend 2: a second port as standard
The request that changes the test matrix.
A second port adds a connector, a control path and a sharing rule, and the sharing rule is what multiplies the test positions. Buyers now expect the rule to be documented rather than discovered.
Trend 3: higher tiers moving into the mainstream
The request that moves the switching stage upward.
As devices adopt higher power profiles, the tiers that were once flagship become the standard offering, and the switching stage that made them possible becomes the baseline rather than a premium.
Trend 4: thermal evidence earlier
The request that moves a measurement into the specification.
Buyers increasingly ask for the temperature rise and the derating threshold with the quotation rather than with the sample, which means the measurement happens during platform selection instead of after it.
Trend 5: a second qualified device
The request that protects the schedule.
Programmes that have experienced a shortage now ask for two qualified switching devices in the approved list. The request is a resilience measure and it costs a qualification rather than a redesign.
| Trend | What it changes | Evidence buyers ask for | Timing |
|---|---|---|---|
| Smaller enclosure | Frequency and thermals | The temperature rise in the enclosure | Platform selection |
| A second port | The sharing rule and test matrix | The sharing table | Specification |
| Higher tiers | The switching stage | The efficiency at load points | Platform selection |
| Thermal evidence | When the measurement happens | Rise and derating with the quotation | Quotation |
| Second device | The approved component list | The qualification record | Before the order |
What buyers are asking less often
Three requests that have declined.
A charger at the highest tier without a size target, because the tier alone no longer differentiates; a single-port product without a sharing consideration, because the channel expects multi-device use; and a certification claim without a scope, because marketplaces now read the scope.
What the trends mean for a programme
Three planning consequences.
Platform selection matters more than the specification sheet, because the enclosure and the thermal position are fixed there; the test plan grows with the port count; and the approved component list is now a resilience document rather than a purchasing one.
Where programmes mismatch the trends
Three patterns, and each is a late decision.
An enclosure chosen after the platform; a second port added after the test plan was written; and a thermal measurement requested after the sample was approved. Each is a sequencing error that the trends above make more expensive.
What the order book says about packaging
Buyers increasingly ask for a multi-language carton in one revision rather than separate packs per market, which moves the work into the layout and away from the print count. The request is a zoning decision rather than a printing one.
What to settle before the quotation
The size target, the port count, the markets and the volume. Those four allow a platform to be proposed with its thermal position and its test matrix rather than a wattage figure with an enclosure to be decided later.
What to bring to the quotation
Bring the size target, the port count, the device list and the volume. Those four allow a platform to be proposed with its thermal position, its test matrix and its component resilience rather than a wattage figure with the enclosure left open.
What the order book shows about the tiers
The requests move up the output range before they move down it. The second port and the higher tiers appear first in the enquiries, and the size target arrives with them rather than after.
The second observation concerns evidence. Buyers ask for the thermal result with the quotation rather than after the sample, which moves the measurement earlier in the programme and changes the order of the work.
The third is the component list. A second qualified switching device is requested as a standard item rather than as a resilience option, which turns the approved list into a document the buyer reads.
A programme that expects those three prepares the platform, the measurement and the component list before the first enquiry rather than during it.
FAQ
Is the second port now expected?
In many channels it is, and the sharing rule is expected with it. The rule defines the test positions, so it is specified rather than discovered. The sharing rule defines the test positions, so it is specified with the port count rather than discovered during the test plan. It is specified with the port count rather than added after the test plan is written.
Why are buyers asking for thermal data earlier?
Because the derating threshold decides what the customer experiences in a warm room, and it is cheaper to know it during platform selection than after the sample is approved. The derating threshold decides what the customer experiences in a warm room, and knowing it during platform selection is cheaper than changing the design afterwards. It is cheaper to know the threshold during platform selection.
Does a second qualified device change the design?
It adds a qualification and possibly a thermal re-measurement rather than a redesign, and it gives the programme an option when supply tightens. It adds a qualification and possibly a thermal re-measurement rather than a redesign, and it gives the programme an option when supply tightens. The qualification records what a substitution would reopen, which is the document the buyer reads.
What has declined?
Single-port products with no sharing consideration, chargers specified by tier without a size target, and claims made without an accompanying scope. Single-port products with no sharing consideration, chargers specified by tier without a size target, and claims made without an accompanying scope. Those three are the requests that have fallen away as the tiers moved up the range and the size target became standard.
