TL494C 7V~40V PWM SMD IC SOIC-16-150mil

Description

TL494C 7V~40V PWM SMD IC SOIC-16-150mil The TL494C is a versatile pulse-width-modulation (PWM) control circuit integrated circuit designed by Texas Instruments for efficient power-supply control. This device incorporates all essential functions required for constructing PWM control circuits on a single chip, offering flexibility to tailor power-supply control to specific applications. It features two error amplifiers, an adjustable on-chip oscillator, a dead-time control comparator, a pulse-steering flip-flop, a precision 5V regulator with 5% tolerance, and output-control circuits. Features: Complete PWM Power-Control Circuitry. Uncommitted Outputs for 200-mA Sink or Source Current. Output Control Selects Single-Ended or Push-Pull Operation. Internal Circuitry Prohibits Double Pulse at Either Output. Variable Dead Time Provides Control Over Total Range. Internal Regulator Provides a Stable 5-V Reference Supply With 5% Tolerance. Circuit Architecture Allows Easy Synchronization.
