The recommended PCB layout for optimal thermal performance involves using a 2-layer or 4-layer board with a solid ground plane, and placing thermal vias under the device to dissipate heat efficiently.
To ensure EMC, use a shielded enclosure, keep the device away from high-frequency sources, and use a common-mode choke or ferrite bead to filter out electromagnetic interference.
The maximum allowed voltage transient on the input pins is 20% above the maximum recommended operating voltage, but it's recommended to use a TVS diode or a voltage clamp to protect the device from voltage spikes.
While the device is rated for operation up to 150°C, it's recommended to derate the current and voltage at higher temperatures to ensure reliable operation and prevent thermal runaway.
Check the input voltage, output voltage, and current sense resistors for correct values and connections. Verify that the enable pin is properly biased, and check for any signs of overheating or physical damage.
