SM91047EL Frequently Asked Questions (FAQs)
Bourns recommends a symmetrical PCB layout with a solid ground plane, and keeping the input and output traces as short as possible to minimize parasitic inductance and capacitance.
To ensure reliable operation in high-temperature environments, it's essential to follow proper thermal management practices, such as providing adequate heat sinking, using thermal interface materials, and keeping the device within its specified operating temperature range.
While the datasheet specifies the maximum operating voltage, it's essential to note that the device can withstand voltage stresses up to 1.5 times the maximum operating voltage for a short duration (typically 100 ms) without damage.
To troubleshoot oscillation or instability issues, check for proper PCB layout, ensure that the input and output capacitors are of suitable value and type, and verify that the device is operated within its specified frequency range and load conditions.
Yes, to minimize EMI/EMC issues, it's recommended to use a shielded enclosure, keep the device away from noise sources, and use proper filtering and shielding techniques for the input and output lines.
