The Texas Instruments TL494I is a versatile pulse-width-modulation (PWM) control circuit integrated onto a single chip, primarily designed for power supply control applications. It offers flexibility to tailor control circuitry to specific needs.
Key features include two error amplifiers, an on-chip adjustable oscillator, a dead-time control (DTC) comparator, and a pulse-steering control flip-flop. The device provides uncommitted outputs capable of 200-mA sink or source current. An internal regulator supplies a stable 5-V reference with 5% tolerance. The output control function allows selection between single-ended or push-pull operation, with internal circuitry preventing double pulsing at either output.
This PWM controller operates over a temperature range of -40°C to 85°C. It is available in a PDIP package suitable for through-hole mounting. The architecture allows for easy synchronization in multiple-rail power supplies.
The TL494I is suitable for various power supply designs requiring precise pulse-width modulation and control.
The maximum supply voltage is 40V.
The typical operating frequency is 300kHz.
The uncommitted outputs can sink or source 200mA.
The internal regulator provides a 5V reference with 5% tolerance.
The TL494I is available in a PDIP package.
The TL494I variant operates from -40°C to 85°C.
