TL494 pulse width modulation control circuit

RF cable can be customized for other specifications

description:

The TL494 is a fixed frequency pulse width modulation circuit that includes all the functions required for switching power supply control. It is widely used in single-ended forward double-tube, half-bridge, full-bridge switching power supplies. The TL494 is available in SO-16 and PDIP-16 packages to suit different applications. Its main features are as follows:

Main feature

• All pulse width modulation circuits are integrated.
• Built-in linear sawtooth oscillator with only two external oscillating components (one battery)
• Resistance and a capacitor).
• Built-in error amplifier.
• Internally rejects the 5V reference voltage source.
• The dead time can be adjusted.
• The built-in power transistor provides 500mA drive capability.
• Push or pull two output methods.
