The recommended PCB layout for optimal thermal performance involves placing the converter on a multi-layer board with a solid ground plane, using thermal vias to dissipate heat, and keeping the surrounding area clear of components to ensure good airflow.
To ensure reliable start-up and shutdown, it is recommended to use a soft-start circuit to limit the inrush current, and to add a delay between the enable signal and the input voltage to prevent voltage spikes.
Operating the converter outside of the recommended input voltage range may affect its efficiency, reliability, and output voltage regulation. It may also lead to reduced lifespan or even damage to the converter.
To protect the converter from overcurrent and overvoltage conditions, it is recommended to add external overcurrent protection (OCP) and overvoltage protection (OVP) circuits, and to ensure that the input voltage and current are within the recommended specifications.
The converter is designed to meet CISPR 22 Class B EMI standards, but additional EMI filtering may be required to meet specific application requirements. It is recommended to follow good EMC design practices, such as using a metal enclosure, shielding, and filtering, to minimize electromagnetic interference.
