The recommended PCB layout for optimal thermal performance involves placing the DC-DC converter near a metal edge or a heat sink, and ensuring good airflow around the component. Additionally, using thermal vias and a solid ground plane can help to dissipate heat efficiently.
To ensure reliable start-up and shutdown of the converter, it is recommended to follow the recommended start-up and shutdown sequences outlined in the datasheet, and to use a soft-start circuit to limit the inrush current during start-up.
Operating the converter outside of the recommended input voltage range can lead to reduced efficiency, increased heat generation, and potentially even damage to the component. It is recommended to operate the converter within the specified input voltage range to ensure reliable operation and to prevent damage.
To troubleshoot issues with the converter's output voltage regulation, check the input voltage, output load, and feedback loop components. Ensure that the input voltage is within the recommended range, the output load is within the specified range, and the feedback loop components are properly connected and functioning correctly.
The CHB350-24S28 is designed to meet CISPR 22 Class B and EN 55022 Class B EMI standards. To ensure compliance, it is recommended to follow proper PCB layout and grounding practices, use EMI filters and shielding, and ensure that the converter is operated within the specified input voltage and output load ranges.
