NCP6343BFCCT1G Frequently Asked Questions (FAQs)
A 2-layer or 4-layer PCB with a solid ground plane and thermal vias is recommended. The device should be placed near a thermal pad or heat sink to dissipate heat efficiently.
Ensure that the input voltage rises and falls monotonically, and that the enable pin is properly biased during start-up and shutdown. A soft-start circuit can also be used to reduce inrush current.
The maximum allowed input voltage ripple is 10% of the nominal input voltage. Exceeding this limit may affect the device's performance and reliability.
Yes, but the device's performance and reliability may be affected above 125°C. Ensure that the device is properly heat-sinked and that the junction temperature is kept below 150°C.
Check the PCB layout for noise coupling, ensure that the output capacitor is properly sized and placed, and verify that the feedback loop is properly compensated. Consult the application note for more information.
