Successful modification of our higher power topologies to the low power adapter area (220W), has resulted in a new benchmark for adapter technology.
We can now offer designs with 12V 18-22A out, continuous, with a footprint and volume only twice that of a common 70W adapter and with universal input. We will be extending the range to higher currents at 12V, 19V, 24V also.
The key to this achievement has been a novel single stage converter removing the input bridge rectifer
Resulting in an efficiency of 95.% at 90VAC, 220W or 265W output.
Common parts are used throughout to ensure a cost friendly design that can be applied to standard manufacturing processes in high volume with excellent repeatability and reliability.
