Bourns provides a recommended PCB layout and land pattern in their application note AN16, which can be found on their website. It's essential to follow these guidelines to ensure proper thermal management, minimize parasitic inductance, and optimize the overall performance of the ISOM5-175-B-L2.
The selection of input and output capacitors depends on the specific application requirements, such as voltage rating, capacitance value, and ESR. Bourns recommends using low-ESR capacitors with a voltage rating of at least 1.5 times the maximum input voltage. A minimum capacitance value of 10uF is recommended for the input capacitor, and 22uF for the output capacitor. Consult the datasheet and application notes for more detailed guidance.
The maximum allowable ambient temperature for the ISOM5-175-B-L2 is 85°C, with a derating of 2.5% per degree above 60°C. It's essential to ensure proper airflow and heat sinking to maintain a safe operating temperature and prevent overheating.
The ISOM5-175-B-L2 is designed to meet the requirements of IEC 60068-2-6, which includes vibration testing. However, it's essential to ensure that the module is properly secured to the PCB and that the PCB is designed to withstand the expected vibration levels. Consult the datasheet and application notes for more detailed guidance.
The typical efficiency of the ISOM5-175-B-L2 is around 85-90% at full load, depending on the input voltage and output load. Efficiency may vary with load and temperature, with a decrease in efficiency at lower loads and higher temperatures. Consult the datasheet and application notes for more detailed efficiency curves and guidance.
