For optimal performance, it's recommended to follow a 2-layer PCB layout with a solid ground plane on the bottom layer. Ensure a minimum of 1 oz copper thickness and a 10 mils (0.25 mm) spacing between the DC-DC converter and other components. Additionally, provide adequate thermal management by using a heat sink or thermal interface material to keep the junction temperature below 125°C.
To ensure EMC, follow proper PCB layout and design guidelines, such as separating analog and digital circuits, using shielding, and minimizing loop areas. Additionally, use a metal enclosure and ensure the converter is at least 1 cm away from other components. Finally, perform EMC testing to ensure compliance with relevant standards.
Derating curves are available upon request from CUI Inc. or through their authorized distributors. To apply the derating curves, determine the maximum ambient temperature and output power required for your application. Then, use the derating curves to determine the maximum output current and voltage that can be safely achieved while maintaining a safe operating temperature.
Yes, the PDM2-S12-S12-S can be used in a redundant or parallel configuration to achieve higher power output or redundancy. However, it's essential to follow proper design guidelines and ensure that the converters are synchronized and properly configured to avoid oscillations or instability.
For optimal performance, use low-ESR capacitors with a minimum capacitance of 10 μF for the input and 22 μF for the output. Ensure the capacitors are rated for the maximum input and output voltages, and follow the recommended layout guidelines to minimize noise and EMI.
