CUI recommends a 4-layer PCB with a solid ground plane, and thermal vias under the device to dissipate heat. A minimum of 1 oz copper thickness is recommended. For thermal management, a heat sink or thermal interface material can be used to reduce thermal resistance.
To ensure EMC, CUI recommends following proper PCB layout guidelines, using a metal enclosure, and implementing EMI filtering on the input and output lines. Additionally, the device should be placed at least 10 mm away from other components to minimize electromagnetic interference.
The maximum allowable ripple current for the SJ-3504 is 30% of the maximum output current. Exceeding this limit may reduce the device's lifespan or cause it to malfunction.
Yes, the SJ-3504 can be used in a redundant or parallel configuration to increase power output or improve reliability. However, it is essential to ensure proper synchronization and current sharing between devices to prevent uneven stress and potential failures.
CUI recommends using a fuse with a rating of 5-10 A, depending on the input voltage and current requirements. The fuse should be able to handle the maximum inrush current during startup and provide adequate protection against overcurrent conditions.
