STMicroelectronics recommends a thermal pad connected to a large copper area on the PCB to dissipate heat efficiently. A minimum of 2oz copper thickness is recommended, and the thermal pad should be connected to a ground plane to reduce thermal resistance.
To ensure stability, it's essential to follow the recommended component values and PCB layout guidelines in the datasheet. Additionally, a minimum output capacitance of 10uF is recommended, and the output voltage should be decoupled with a 10nF capacitor to prevent oscillations.
Although the datasheet specifies a maximum input voltage of 5.5V, it's recommended to limit the input voltage to 5V to ensure reliable operation and prevent damage to the device.
The TSV620AICT is rated for operation up to 125°C, but it's essential to consider the thermal derating curve in the datasheet to ensure reliable operation. Additionally, the device should be derated to 80% of its maximum output current at high temperatures to prevent overheating.
To troubleshoot output voltage errors, check the input voltage, output load, and PCB layout for any issues. Verify that the output voltage is within the specified tolerance, and check for any signs of overheating or oscillations. If the issue persists, consult the application note or contact STMicroelectronics support for further assistance.
