Key Features
- Supports multiple converter topologies — buck, boost, flyback, forward, full-bridge, half-bridge, and push-pull — in a single versatile controller
- Voltage-mode PWM control with 7 V to 40 V input range and 250 mA peak output current for driving external power switches
- 16-pin SSOP package reduces board area compared to DIP alternatives while maintaining full TL494 pin compatibility
Applications
The TL494CDBR is widely used in switch-mode power supply (SMPS) designs for industrial equipment, telecommunications power systems, and computer peripherals requiring flexible multi-topology support. Its voltage-mode PWM control and wide input voltage range make it suitable for designing AC-DC adapters, DC-DC converters, and battery chargers. The device is also popular in motor drive pre-driver stages and uninterruptible power supply (UPS) inverter sections where reliable PWM generation is essential.

Frequently Asked Questions
What converter topologies does the TL494CDBR support?
The TL494CDBR supports buck, boost, flyback, forward, full-bridge, half-bridge, and push-pull converter topologies, making it one of the most versatile PWM controller ICs available for switch-mode power supply design.
What is the input voltage range and output current of the TL494CDBR?
The TL494CDBR operates with an input voltage range of 7 V to 40 V (nominal 15 V) and provides up to 250 mA peak output current to drive external switching transistors or MOSFETs in power converter circuits.
What control method does the TL494CDBR use?
The TL494CDBR uses voltage-mode pulse width modulation (PWM) control, varying the duty cycle of the output pulses to regulate the power converter output voltage with stable closed-loop feedback performance.
What package is the TL494CDBR available in?
The TL494CDBR comes in a 16-pin SSOP (Shrink Small Outline Package) which is smaller than the traditional DIP-16 package, reducing PCB area while maintaining the same proven TL494 circuit functionality.
What are typical applications for the TL494CDBR?
