The recommended PCB layout for the TDA2611A involves keeping the input and output tracks as short as possible, using a ground plane, and placing decoupling capacitors close to the IC. A star-point earthing system is also recommended to minimize noise and hum.
The bootstrap capacitor value depends on the output power and the switching frequency. A general rule of thumb is to choose a capacitor with a value between 10nF to 100nF. A higher value can be used for higher output power, but it may increase the turn-on time.
The maximum allowed voltage on the bootstrap pin is typically around 35V, but it's recommended to keep it below 30V to ensure reliable operation and prevent damage to the IC.
To prevent overheating, ensure good heat dissipation by using a heat sink, keeping the ambient temperature below 70°C, and reducing the power dissipation by optimizing the circuit design and component selection.
The recommended input voltage range for the TDA2611A is between 12V to 18V, but it can operate with input voltages as low as 9V and as high as 24V. However, the output power and efficiency may be affected at these extremes.
