The TL494 is a fixed-frequency pulse-width modulation (PWM) control circuit designed primarily for power supply applications. It contains all the functions necessary for single-ended or push-pull switching power supplies: an on-chip oscillator with external timing components (RT and CT), two error amplifiers, a 5V precision reference (VREF), a dead-time control (DTC) comparator, a pulse-steering flip-flop, and dual output transistors capable of sourcing or sinking up to 200mA. These two outputs can operate in either push-pull or parallel mode, making the TL494 incredibly flexible. Connect OUTPUT CTRL to GND
