DC to DC Converter 12V to ± 38V

DC to DC Converter 12V to ± 38V
The core of the Car DC to DC Converter 12V to ± 38 VDC is a pulse generator built on the TL494 chip. The circuit is designed to provide power supply to Monoblock Car Amplifier TDA7294. Generator frequency can be changed by varying the resistor R3. Optionally, you can download the datasheet and find out more details on chips. (more…)
