TDK recommends a 4-layer PCB with a solid ground plane and a separate power plane for the HHM1517. The component should be placed near the power source, and the input and output capacitors should be placed as close as possible to the device.
Ensure good airflow around the device, and consider using a heat sink if the device is expected to operate in high-temperature environments. Also, follow the recommended thermal design guidelines provided by TDK.
TDK recommends using a low-ESR ceramic capacitor with a value of 10uF to 22uF, depending on the specific application requirements. The capacitor should be placed as close as possible to the VIN pin of the HHM1517.
Check the input voltage, output load, and PCB layout for any issues. Verify that the device is properly soldered and that there are no signs of physical damage. Consult the TDK application notes and datasheet for troubleshooting guidelines.
Yes, the HHM1517 is designed for high-reliability applications. However, it's essential to follow TDK's guidelines for design, manufacturing, and testing to ensure the device meets the required safety and reliability standards.
