The TL494 is a versatile Pulse-Width-Modulation (PWM) control circuit integrated onto a single chip, designed primarily for power supply control. It incorporates essential functions including two error amplifiers, an adjustable oscillator, a dead-time control comparator, a pulse-steering control flip-flop, and a 5V precision regulator.
Key electrical characteristics include a stable 5V reference supply with 5% tolerance and uncommitted outputs capable of 200mA sink or source current. The device architecture allows for selection between single-ended or push-pull operation and prevents double pulsing at either output. It is characterized for operation from 0°C to 70°C for commercial applications and -40°C to 85°C for industrial applications.
The TL494 is available in multiple package types, including SOIC, PDIP, SOP, and TSSOP, all with 16 pins. Its design flexibility makes it suitable for a wide range of applications, including desktop PCs, microwave ovens, server PSUs, and solar power inverters.
The TL494 has an internal regulator that provides a stable 5-V reference supply with a 5% tolerance.
The uncommitted outputs of the TL494 can provide 200-mA sink or source current.
The TL494 is characterized for operation from 0°C to 70°C.
The TL494 is available in SOIC, PDIP, SOP, and TSSOP packages, all with 16 pins.
