TL494CN PWM Controller IC – DIP16
The TL494CN is a fixed-frequency pulse-width modulation (PWM) controller IC designed for switching power supplies and power control applications. It integrates the main control functions required to generate PWM signals, allowing designers to develop power supply circuits with adjustable operating parameters. The IC includes two error amplifiers, an adjustable on-chip oscillator, a dead-time control comparator, a pulse-steering control flip-flop, a 5 V reference regulator, and output control circuits.
