Texas Instruments TL494CDR - PWM Controller IC
The TL494CDR is a pulse-width modulation (PWM) control circuit from Texas Instruments (TI), designed for switching power supply and DC-DC converter applications. It provides adjustable frequency and duty cycle control, making it a versatile choice for power management systems.
TL494CDR Key Features
- Adjustable PWM frequency (up to 300 kHz)
- Push-pull or single-ended output modes
- On-board error amplifiers for voltage/current feedback control
- Dead-time control (prevents shoot-through in bridge circuits)
- Wide operating voltage range (7V to 40V)
- Thermal shutdown protection
- Available in SOIC-16 package
TL494CDR Applications
- Switched-mode power supplies (SMPS)
- DC-DC converters (buck, boost, flyback)
- Motor speed controllers
- Inverters & UPS systems
- LED drivers
- Reliable & industry-proven design (widely used since the 1980s)
- Flexible configuration (supports multiple control schemes)
- Robust protection features (overcurrent, overtemperature)
