The TL494CJ is a versatile PWM (Pulse-Width Modulation) control circuit manufactured by Texas Instruments. It is designed to provide complete PWM power-control circuitry for a wide range of applications, including desktop PCs, microwave ovens, and power supplies greater than 90W.
Key electrical specifications include a maximum input voltage of 40V, a minimum input voltage of 7V, and a maximum switching frequency of 300kHz. The device features uncommitted outputs capable of 200mA sink or source current and provides control for single-ended or push-pull operation. It also includes internal circuitry to prevent double pulsing at either output and offers variable dead time control.
This PWM controller integrates an internal regulator that supplies a stable 5V reference with a 5% tolerance. The circuit architecture allows for easy synchronization. The TL494CJ is packaged in a 16-CDIP through-hole configuration with a lead spacing of 2.54mm.
Applications for the TL494CJ include AC/DC power supplies, isolated power supplies with PFC, and server PSUs. Its robust design and feature set make it suitable for demanding power management tasks.
