The power converter can be as simple as a transformer or it can be a far more complex system, such as resonant converter. The L6983i is in production now, in a 3mm x 3mm QFN16 package, and is available from $1.38 for orders of 1000 pieces. A power converter can convert alternating current (AC) into direct current (DC) and vice versa change the voltage or frequency of the current or do some combination of these. ![]() The evaluation board, STEVAL-L6983IV1, helps designers explore the features of the L6983i quickly and accelerate the time to market for new projects. It can be used to power isolated gate drivers for IGBTs and silicon-carbide (SiC) or gallium-nitride (GaN) transistors, industrial automation, small traction systems and charging stations, and isolated safety equipment. The selectable spread-spectrum feature improves EMC performance.Ĭapable of sourcing/sinking up to 4.5A primary current, the L6983i allows the switching frequency to be adjusted from 200kHz to 1MHz and to be also externally synchronized. It implements an iso-buck topology, which uses fewer components than a conventional isolated flyback converter and requires no optocoupler, saving bill-of-materials costs and PCB space.įurther benefits of the L6983i include 2♚ shutdown current and integrated functions such as adjustable soft-start time, internal loop compensation and power good indicator, as well as protection from overcurrent and thermal shutdown.
