TL494BD General Description
The TL494BD by Texas Instruments is a versatile pulse-width modulation controller IC that is ideal for a wide range of applications, including power supply and motor control. With a frequency range of up to 500 kHz and a voltage supply range of 7V to 40V, this IC offers precise voltage regulation and efficient control over power transistors. The built-in error amplifier with a fixed 2.5V reference voltage ensures accurate voltage regulation, while the pulse-width modulation comparator and dead-time control comparator allow for fine-tuning of the output signal. Moreover, the high-current totem pole output stage delivers reliable performance in driving power transistors
