Quality Control: Learn More

The Texas Instruments TL494CDG4 is a versatile 16-SOIC dual-edge-triggered pulse-width modulation (PWM) controller. This component is designed for DC-DC conversion applications across various topologies including buck, boost, flyback, forward converter, full-bridge, half-bridge, and push-pull configurations. It supports step-up, step-down, and step-up/step-down voltage regulation. The TL494CDG4 features independent control over the output pulse width of two or more output channels, with a maximum duty cycle of 45%. Key control features include dead time and frequency control, with a selectable switching frequency range from 1kHz to 300kHz. This device operates with a supply voltage range of 7V to 40V and provides two transistor driver outputs. The TL494CDG4 is suitable for use in power supply systems, motor control, and lighting applications.
