TL494CN Description

Short technical summary and product information.

The TL494CN is a fixed-frequency, pulse-width modulation (PWM) control circuit from Texas Instruments, primarily designed for SWITCHMODE power supply control applications. This integrated circuit features on-chip oscillator, error amplifiers, and a 5.0 V reference. It supports adjustable deadtime control and offers output control for push-pull or single-ended operation.

 

Key electrical specifications include a wide operating voltage range from 7V to 40V, with a maximum power supply voltage rating of 42V. The device operates within an ambient temperature range of 0°C to 70°C. Its frequency can be adjusted from 1kHz to 300kHz, with a maximum duty cycle of 45%. The TL494CN supports multiple topologies including Buck, Boost, Flyback, Forward Converter, Full-Bridge, Half-Bridge, and Push-Pull configurations.

 

Packaged in a 16-PDIP through-hole component, the TL494CN is suitable for various power supply designs. It features two outputs and a transistor driver output type. The control features include dead time control and frequency control, enhancing its versatility in power management applications.
