Pin 3 (FEEDBACK) is highly sensitive. Place your RC compensation network physically close to Pins 2 and 3 to shield the system from electromagnetic interference (EMI).

The TL494 circuit consists of several key components:

The is a versatile and cost-effective pulse-width-modulation (PWM) control IC that has been a staple in power electronics for decades. Designed primarily for switch-mode power supply (SMPS) control, it offers a complete set of functions—including an adjustable oscillator, two error amplifiers, and dead-time control—on a single chip.
