TL494 Pulse Width Modulation Controller IC SMD

TL494 Pulse Width Modulation Controller IC SMD

The TL494 is a versatile and widely used Pulse Width Modulation (PWM) Controller IC designed for switch-mode power supply (SMPS) and DC–DC converter applications. Developed by Texas Instruments, this device integrates all the necessary control circuitry to implement fixed-frequency PWM control, including two error amplifiers, a dead-time comparator, an on-chip oscillator, a reference regulator, and output control logic.

Housed in a compact SMD package, the TL494 offers high efficiency, excellent load regulation, and precise duty-cycle control, making it ideal for designing efficient and reliable power conversion systems.
