The maximum power dissipation of the TDA1560Q/N4C,112 is 2.5 W. However, it's recommended to keep the power dissipation below 2 W to ensure reliable operation.
The input capacitor value depends on the input voltage, output voltage, and output current. A general rule of thumb is to choose a capacitor with a value between 1-10 μF, with a voltage rating higher than the input voltage. For example, for a 12 V input and 5 V output, a 2.2 μF capacitor with a 25 V rating would be suitable.
The minimum ESR requirement for the output capacitor is 0.1 Ω. However, it's recommended to use a capacitor with an ESR of 0.05 Ω or lower to ensure stable operation.
The TDA1560Q/N4C,112 is rated for operation up to 125°C. However, it's recommended to derate the power dissipation at higher temperatures to ensure reliable operation. A general rule of thumb is to derate the power dissipation by 1% per degree Celsius above 85°C.
To ensure stability, make sure to follow the recommended PCB layout guidelines, use a sufficient output capacitor value, and keep the input and output capacitors close to the device. Additionally, avoid using long traces and minimize the loop area of the power traces to reduce electromagnetic interference (EMI).
