A good PCB layout for the TSM9926DCS should prioritize thermal dissipation. Place the device near a thermal pad or a heat sink, and ensure that the PCB has sufficient thermal vias to dissipate heat efficiently. A 4-layer PCB with a dedicated thermal layer is recommended.
To ensure reliable operation in high-temperature environments, follow the recommended operating conditions, and consider using a heat sink or thermal pad to keep the junction temperature below 150°C. Also, ensure that the device is properly soldered and the PCB is designed to minimize thermal resistance.
Although the datasheet specifies the recommended operating voltage range, it's essential to note that the maximum allowed voltage on the input pins is 6V. Exceeding this voltage may damage the device or affect its reliability.
To troubleshoot issues with the output voltage regulation, check the input voltage, output load, and PCB layout. Ensure that the input voltage is within the recommended range, the output load is within the specified current limit, and the PCB layout is optimized for thermal performance. Also, verify that the device is properly soldered and the output capacitors are of sufficient value and quality.
Yes, the TSM9926DCS is a sensitive device and requires proper ESD protection measures during handling, assembly, and operation. Use ESD-safe materials, follow proper handling procedures, and consider adding ESD protection devices, such as TVS diodes, to the PCB design.
