Voltage-driven pulse width modulator TL494
Characteristics and functions of TL494
TL494 is a voltage-driven pulse width modulator produced by Texas Instruments in the United States. It can be used as a switching power supply circuit in system circuits such as monitors and computers. The output transistor of TL494 can be connected to a common There are two modes of emitter and emitter follower, so you can choose double-ended push-pull output or single-ended output mode. In push-pull output mode, its two drive pulses are 180 degrees apart, while in single-ended mode, its two drive pulses are 180 degrees apart. The two driving pulses are of the same frequency and phase.
The internal functional block diagram of TL494 is shown below:

1IN+, 1IN-, 2IN+, 1IN- input; FEEDBACK feedback; DTC dead time control; CT timing capacitor; RT timing resistor; GND ground; C1, C2 collector 1, 2; E1, E2 emitter 1, 2; Vcc Power supply; OUTPUT CTRL output control; REF reference.
