Efficiently Control Power Supplies with TL494CDR PWM Control Circuit

The TL494CDR is a highly integrated device that combines all the essential functions required to build pulse width modulation (PWM) control circuits, commonly used in power supply applications. This single-chip solution incorporates two error amplifiers, an adjustable oscillator, a dead time control (DTC) comparator, a pulse steering control flip-flop, a 5V regulator with 5% tolerance, and output control circuitry.

All-in-One Solution for PWM Power Control: TL494CDR PWM Control Circuit

Designed for versatility, the TL494CDR offers both push-pull and single-ended output operations, selectable through the output control feature. Its internal circuitry ensures the inhibition of double pulses at either output, guaranteeing reliable performance. The variable dead time feature provides precise control over a wide range, allowing customization to meet specific application requirements.

With an internal regulator providing a stable 5V reference supply with 5% tolerance, the TL494CDR simplifies design implementation. Its circuit architecture enables easy synchronization, facilitating system integration and synchronization with external components.
