TL494 Integrated Circuit – DIP Package

The TL494 is a versatile pulse-width modulation (PWM) control IC commonly used in switch-mode power supplies and DC-DC converters. It integrates all the necessary functions to implement a PWM regulator, including error amplifiers, an oscillator, a dead-time control comparator, and output control circuitry.

Key Features

• Adjustable PWM duty cycle with built-in dead-time control
• Two error amplifiers for feedback control
• On-chip oscillator with adjustable frequency
• Output control for push-pull, single-ended, or parallel operation
• Under-voltage lockout for stable startup
• Wide supply voltage range (7V to 40V)
• DIP package for easy prototyping and integration

Applications

• Switch mode power supplies (SMPS)
• DC-DC converters
• Motor speed control
• Battery chargers
• LED dimming circuits
