Part Number : TL494
Function : 40V, 0.2A, 300KHz, Pulse-Width-Modulation Control Circuits
Package : DIP 16 Pin Type
Maker : Texas Instruments
Pinouts : 
Description :
The TL494 device incorporates all the functions required in the construction of a pulse-width-modulation (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
