XP Power recommends a PCB layout with a large copper area connected to the tab of the device to dissipate heat effectively. A minimum of 1 oz copper thickness is recommended, and the copper area should be at least 1 inch x 1 inch in size.
To ensure reliable start-up, XP Power recommends a soft-start circuit or a ramp-up of the input voltage to prevent high inrush currents. Additionally, the input voltage should be within the specified range, and the output should be properly decoupled with capacitors.
The maximum allowed capacitance on the output of the STS1024S09 is 2200uF. Exceeding this value may cause instability or oscillation in the converter.
While the STS1024S09 is rated for operation up to 85°C, XP Power recommends derating the output power by 2.5% per degree above 70°C to ensure reliable operation. Additionally, the device should be mounted on a heat sink to dissipate heat effectively.
To troubleshoot issues with the STS1024S09, XP Power recommends checking the input voltage, output voltage, and output current. Verify that the input voltage is within the specified range, and the output voltage is within the specified tolerance. Check for any signs of overheating, such as excessive temperature or burning smells. Consult the datasheet and application notes for further guidance.
