Pwm Ic Tl494. The tl494 ic is a fixed frequency current mode pwm controller ic with all the functions that are required in the construction of the pulse width modulation pwm control circuit on a single chip. It comprises of on chip two error amplifiers an oscillator with adjustable frequency feature an output flip flop having pulse steering control and an output control circuit with feedback.
The ic tl494 is an ideal pwm ic which is intended essentially to match all sorts of circuits which necessitate accurate pwm dependent outputs. The chip possesses all the needed capabilities built in for creating genuine pwms which can be customized according to the customers utility specifications. It is similar to sg3525 in many ways and can be used as an effective replacement for it although the pin numbers can be different and not exactly compatible.
