Optimizing a PCB Layout for an iPOWIR Technology Design by David Jauregui, International Rectifier reduces any ringing due to stray inductance during switching. Output inductor and filter caps placement have the second order of importance. Placement should be relatively close to the iPOWIR block, but it is not critical. Introduction Although iPOWIR technology based designs represent a unique class of power solutions, the design of the printed circuit board (PCB) is a simple but effective means of optimizing the performance of an iPOWIR solution. In general, there are a number of issues that need to be considered when designing a power supply layout. These issues apply to both discrete ……
