CUI Devices recommends a 4-layer PCB with a solid ground plane, and to keep the input and output traces as short as possible to minimize EMI and noise. Additionally, it's recommended to use a common mode choke and a 10uF capacitor on the input side to filter out noise.
To ensure the SP-3540B operates within the specified temperature range, it's essential to provide adequate heat sinking and airflow. The device should be mounted on a heat sink with a thermal resistance of less than 10°C/W, and the ambient temperature should be kept below 70°C.
Although the datasheet specifies a maximum input voltage of 40V, it's recommended to limit the input voltage to 36V to ensure reliable operation and to prevent damage to the device.
Yes, the SP-3540B can be used in a parallel configuration to increase output current. However, it's essential to ensure that the output voltages of each device are matched within 1% to prevent current imbalance and reduce the risk of oscillation.
CUI Devices recommends using a 10uF to 22uF ceramic or film capacitor with a voltage rating of at least 50V. The capacitor should be placed as close as possible to the input pins to minimize EMI and noise.
