NXP has developed the GreenChip, which is to prevent wasting energy during the charging of notebooks. The chip is intended for use in power supplies of 75 watt and less. This includes PSUs for netbooks, LCD-monitors and small portable printers.
The GreenChip monitors the required power and allows no more than that to pass through. This prevents the power supply from generating heat, which usually indicates loss of power. Because of the chip's switch function, it'll also become possible to make the power supply adaptor smaller, whilst retaining the same capacity.
The GreenChips are manufactured in NXP's factory in Nijmegen. The launched chip is to be the first in a series of power-saving IC's.
