About TL494CDR

The TL494CDR is a dual PWM controller manufactured by Texas Instruments. It is specifically designed for power supply applications and provides precise control over output voltage and current. With a maximum voltage rating of 40V, it can handle high-power requirements efficiently. The TL494CDR operates at a frequency of 300 kHz, allowing for fast switching and reducing power loss.

This PWM controller operates in voltage mode, which means it regulates the output voltage based on a feedback signal. This ensures stable and accurate voltage regulation, making it suitable for various power supply designs. The TL494CDR comes in a SOP16 package, which is a small outline package with 16 pins. This compact packaging makes it convenient for space-constrained applications.

Furthermore, the TL494CDR is compliant with the Restriction of Hazardous Substances (RoHS) directive. This means that it is free from hazardous substances such as lead, mercury, and cadmium, making it environmentally friendly and safe to use. With its dual PWM channels and high voltage and frequency capabilities, the TL494CDR is an ideal choice for power supply applications that require precise control and efficient operation.
