For optimal performance, it's recommended to follow a 4-layer PCB stackup with a dedicated ground plane and thermal vias under the device. Ensure a minimum of 1 oz copper thickness and a thermal pad size of at least 2x2 mm. Additionally, provide a heat sink with a thermal resistance of ≤ 10°C/W and a minimum airflow of 200 LFM.
To handle the high current surge during startup, it's recommended to use a soft-start circuit or an inrush current limiter. This will help reduce the stress on the device and prevent damage. Additionally, ensure that the input capacitors are rated for high ripple current and have a low ESR.
The maximum allowable voltage deviation on the input is ±10% of the nominal input voltage. Exceeding this deviation may affect the device's performance, efficiency, and reliability.
Yes, the SDF-70J can be used in a parallel configuration to increase the output power. However, it's essential to ensure that the devices are matched in terms of their electrical characteristics and that the output currents are balanced. Additionally, a master-slave configuration or a dedicated current sharing circuit may be required to prevent uneven current distribution.
For compliance with EMC standards, it's recommended to use a common-mode choke with a minimum inductance of 10 μH and a maximum impedance of 100 Ω. Additionally, use X-capacitors with a minimum capacitance of 10 nF and a maximum voltage rating of 250 VAC. Ensure that the EMI filter is placed close to the device and that the layout is optimized for minimal radiation.
