Reduce power supply voltage at 40V output | To reduce the voltage of the Panasonic sound power supply so it doesn't burn out TPS54240 Regulator, First place a 4k7 resistor pin 5v connected to pin 12 PCONT of the power supply, I just soldered it, I turned on the test power supply it was giving 38.4 V output, I reduced it near IC1701 pin 1 to 4 resistors in series 182 = 1K8 / 0 ohm /333=33k /0 ohm, I just replace 1k8 for 15k and 33k 10k, I did the procedure and turned on the power supply, voltage dropped to 32.1V. | It doesn't go beyond the TPS54240, sound working normally | Andre |
