NVE recommends a 4-layer PCB with a solid ground plane, and to keep the IL716E away from high-current carrying traces. Additionally, use a low-ESR capacitor (e.g., 100nF) between VCC and GND, and a 1kΩ resistor in series with the output to reduce ringing.
NVE recommends using a heat sink or thermal pad to keep the junction temperature below 125°C. Ensure good airflow, and consider using a thermal interface material (TIM) to improve heat transfer. Also, derate the output current according to the temperature derating curve in the datasheet.
The recommended input voltage range is 4.5V to 5.5V. The output voltage is proportional to the input voltage, with a typical output voltage of 1.5V to 2.5V for a 5V input. Ensure the input voltage is within the recommended range to maintain output voltage regulation.
Check the input voltage, output load, and PCB layout for any issues. Verify that the input capacitor is properly sized and placed. Use an oscilloscope to measure the output voltage and check for noise or oscillations. Consult the NVE application note AN-13 for troubleshooting guidelines.
Yes, the IL716E can be used in redundant or fault-tolerant systems. However, ensure that the output voltage is properly synchronized and monitored to prevent voltage conflicts or oscillations. Consult with NVE or a qualified engineer to design a reliable and fault-tolerant system.
