SL Power Electronics recommends a 2-layer PCB with a solid ground plane on the bottom layer and a thermal relief pattern on the top layer to ensure optimal thermal performance.
To ensure reliable start-up and shutdown, it is recommended to add a soft-start circuit to limit the inrush current and to use a power-on reset circuit to ensure the power supply starts up in a known state.
The maximum allowable capacitance for the output filter capacitors is 220uF. Exceeding this value may cause instability in the power supply.
While the datasheet recommends a specific type of input capacitor, other types may be used as long as they meet the specified voltage and capacitance ratings. However, this may affect the power supply's performance and reliability.
SL Power Electronics provides a troubleshooting guide in the application note AN-101, which covers common issues such as overvoltage, undervoltage, and overheating.
