The TL494 by JSMSEMI is a versatile pulse-width-modulation (PWM) control circuit integrated onto a single chip. It is primarily designed for power-supply control, offering flexibility for various applications. Key features include uncommitted outputs capable of 200-mA sink or source current, an internal 5-V reference supply with 5% tolerance, and variable dead-time control.
The device architecture prohibits double pulsing at either output, ensuring reliable operation. It supports both single-ended and push-pull operation modes, selectable via the output-control function. The TL494 is characterized for operation from 0°C to 70°C.
This switching controller is commonly found in applications such as desktop PCs, microwave ovens, server PSUs, and solar power inverters. It is available in a SOP-16 package, suitable for surface-mount designs.
