The integrated inductor in the EN5394QI contributes to noise reduction by significantly helping to reduce noise in the power converter solution. This feature enhances productivity by offering greatly simplified board design, layout, and manufacturing requirements .

The EN5394QI is a synchronous, programmable power supply with integrated power MOSFET switches and integrated inductor. It is designed for point of load regulation for low-power processors, network processors, DSPs, FPGAs, and ASICs, among other applications. The converter has a nominal input voltage range of 2.375-6.6V and can provide up to 9A of continuous output current. It uses a low-noise PWM topology and has a feedback control loop that is voltage-mode type III. The EN5394QI is specifically designed to meet the precise voltage and fast transient requirements of high-performance applications such as set-top boxes/HD DVRs, LAN/SAN adapter cards, and audio/video equipment.
