New dc-dc converters that are bidirectional can eliminate the need for bulky transformers in these applications while bringing more efficient operation. ANKUR PATEL VICOR CORP. ALTERNATIVE energy scenarios involving renewable sources are characterized by the sending of power both […]
Why power modules can work better
than discrete power circuits
The example of an ISL8203M power module shows how designers typically size up the decision between devising a power circuit using discrete components versus spec’ing–in a ready-to-go module. Jian Yin, Intersil Corp. Power modules are the way to go when it comes to getting your design to market quickly, but choose wisely. Power-module architecture choices […]
