Pulse width modulation control circuit chip TL494 Chinese data [Copy link]

TL494 pulse width modulation control circuit chip (Chinese) TL494 is a fixed frequency pulse width modulation circuit, which includes all the functions required for switching power supply control and is widely used in single-ended forward dual-tube, half-bridge, and full-bridge switching power supplies. TL494 has two packaging forms, SO-16 and PDIP-16, to meet the requirements of different occasions. Its main features are as follows: Main features integrate all pulse width modulation circuits. The chip has a built-in linear sawtooth oscillator, and only two external oscillation components (a resistor and a capacitor). Built-in error amplifier. Internal 5V reference voltage source. Adjustable dead time. Built-in power transistor can provide 500mA driving capability. Push or pull output.
