Product Description
The Texas Instruments TL494CNSRG4 is a versatile pulse-width modulation (PWM) switching controller designed for a wide range of power supply and DC-DC converter applications. As part of the proven TL494 series, this integrated circuit combines essential power-management functions into a single device, simplifying the design of efficient switching power supplies.
Supporting multiple converter topologies including buck, boost, flyback, forward, and push-pull configurations, the TL494CNSRG4 provides flexible control for power conversion systems. The device features dual output transistors, adjustable duty cycle control, integrated oscillator functionality, and error amplification circuitry to help designers achieve stable and efficient power regulation.
With a maximum switching frequency of 300kHz and support for output voltages up to 40V, the TL494CNSRG4 is ideal for switched-mode power supplies (SMPS), battery chargers, industrial power systems, inverters, LED drivers, and power management applications.
