Development of Power Inductors to Boost Operation time of Mobile Device Display
ALPS Green Devices has developed two new series of Liqualloy™ chip type power inductors the “GLCLK” and “GLCLM”. The two series were made using original powder compacting and molding technology plus altering the composition of the Liqualloy material used in earlier company’s green products, resulting in three fold increase in frequency characteristics over earlier products while supporting the use of switched mode power supplies with higher frequencies.
The products also achieve a core loss reduction of around 70% at 3MHz resulting in high efficiency in power supply circuits with high ripple current ratios, particularly in display power supplies.
Electrodes in the products are placed on the base achieving low height so the noise suppression components or other parts can be installed within close proximity to them resulting in flexibility in end product design.
