The recommended operating voltage range for the TDA4661 is 8V to 18V, although it can operate up to 20V with reduced performance.
To ensure stable operation in high-temperature environments, it is recommended to use a heat sink with a thermal resistance of less than 10°C/W and to keep the junction temperature below 150°C.
The maximum output current that the TDA4661 can deliver is 1.5A, although this may be limited by the external components and the application circuit.
The value of the external compensation capacitor (C2) depends on the output voltage and the desired stability margin. A general rule of thumb is to use a value between 10nF and 100nF, with a higher value providing greater stability but slower response time.
Yes, the TDA4661 can be used in switching regulator applications, but it is not optimized for high-frequency switching and may require additional external components to ensure stability.
