The TL494IN from Texas Instruments is a comprehensive pulse-width-modulation (PWM) control integrated circuit designed for power supply applications. It integrates essential functions including two error amplifiers, an on-chip adjustable oscillator, a dead-time control comparator, a pulse-steering control flip-flop, a 5V precision regulator, and output control circuits.
This device supports a wide input voltage range from 7V to 40V and operates efficiently across a temperature range of -40°C to 85°C. It features uncommitted outputs capable of 200mA sink or source current and provides control over variable dead time, allowing for tailored power supply circuitry. The TL494IN supports various topologies including Buck, Boost, Flyback, Forward Converter, Full-Bridge, Half-Bridge, and Push-Pull operations.
Packaged in a 16-DIP (Dual In-line Package) with a 0.300" width, the TL494IN is suitable for through-hole mounting. Its architecture prohibits double pulsing at either output, enhancing operational safety. The internal 5V regulator provides a stable reference supply with a 5% tolerance, simplifying external component requirements.
