If the output voltage exceeds target calculations under zero-load conditions, verify that the Error Amplifier output on Pin 3 is not clamped high. A minimum dummy load resistor across the output filter capacitors is recommended to maintain loop stability.
A highly stable internal reference voltage supply ( VREFcap V sub cap R cap E cap F end-sub ) that outputs tolerance, capable of sourcing up to for external biasing networks. tl494 circuit diagram
The TL494 circuit diagram works as follows: If the output voltage exceeds target calculations under
This schematic is standard for car audio amplifiers boosting 12V DC up to split symmetrical rails using an isolation transformer. tl494 circuit diagram
