The maximum output power of LNK626DG-TL is dependent on the input voltage, output voltage, and other design parameters. However, as a general guideline, it can deliver up to 12W of output power with an input voltage range of 85-265VAC.
To ensure safe operation, it's essential to provide adequate heat sinking and thermal management. The device has a maximum junction temperature of 150°C. Ensure that the PCB design and layout allow for good airflow, and consider using a heat sink if necessary.
The recommended input capacitor value is 2.2uF to 4.7uF, X-capacitor type (e.g., X2 or X1) with a voltage rating of at least 250VAC. This ensures that the device can handle the input voltage and provides adequate filtering.
To optimize output voltage regulation, ensure that the output capacitor value is within the recommended range (2.2uF to 10uF), and the output voltage sense resistors are properly selected. Additionally, consider using a voltage feedback network to improve regulation.
To minimize EMI, ensure that the input and output filters are properly designed and implemented. Use a common-mode choke, and consider adding a differential-mode filter. Additionally, ensure that the PCB layout is optimized for EMI reduction.
