Description
The TL494 device incorporates all the functions required in the
construction of a pulse-widthmodulation (PWM) control circuit on a
single chip. Designed primarily for power-supply control, this
device offers the flexibility to tailor the power-supply control
circuitry to a specific application.
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
