Description
TL494CN PWM Control IC
The TL494 is a fixed-frequency pulse-width-modulation controller designed primarily for switching power-supply control. It integrates two error amplifiers, an adjustable oscillator, dead-time control, a pulse-steering flip-flop, a 5 V reference regulator and output-control circuits.
The IC supports single-ended or push-pull output operation. Select the manufacturer option above: Generic or Texas Instruments. The source listing offers two separate variants.
See the Texas Instruments TL494 datasheet for electrical limits, pin functions and application guidance. The controller IC is not a complete power supply; switching power designs require appropriate isolation, feedback, protection and thermal design.
