Cosel recommends a PCB layout with a large copper area connected to the tab of the SUS31205BP to ensure good heat dissipation. A minimum of 1 oz copper thickness is recommended, and the copper area should be at least 1 inch x 1 inch in size.
Yes, the SUS31205BP is designed to withstand high-vibration environments. However, it's essential to ensure that the module is properly secured to the PCB and that the PCB is designed to withstand the vibration levels. Cosel recommends following the IPC-9592 standard for vibration testing.
Cosel provides a derating curve in the datasheet, but it's essential to note that the curve is based on a 30-minute operation at the specified temperature. For longer operation times, it's recommended to derate the output power further to ensure reliable operation.
Yes, it's possible to parallel multiple SUS31205BP modules to increase the output power. However, it's essential to ensure that the modules are identical and that the output voltage is matched within 1% to prevent uneven current sharing. Cosel recommends using a master-slave configuration with a single output voltage sense point.
Cosel recommends using a fuse with a rating of 5A to 10A, depending on the input voltage and the system's fault current requirements. The fuse should be able to handle the inrush current of the module during startup.
