The Texas Instruments TL494ING4 is a versatile pulse width modulation (PWM) controller designed for a wide range of DC-DC switching converter topologies, including buck, boost, flyback, forward converter, full-bridge, half-bridge, and push-pull configurations. This device supports step-up, step-down, and step-up/step-down voltage regulation with positive output. Key control features include adjustable dead time control and frequency control, with a switching frequency range of 1kHz to 300kHz. The TL494ING4 operates from a supply voltage of 7V to 40V and provides a maximum duty cycle of 45%. It features two outputs and a single output phase, configured as transistor drivers. This component is suitable for applications in power supplies, motor control, and lighting systems. The TL494ING4 is supplied in a 16-pin DIP (0.300" wide) package for through-hole mounting and operates within an ambient temperature range of -40°C to 85°C.
