TL494CN Description

Short technical summary and product information.

The TL494CN is a fixed-frequency, pulse-width modulation (PWM) control circuit primarily designed for SWITCHMODE power supply control. Manufactured by ON Semiconductor, this component integrates complete PWM control circuitry, including an on-chip oscillator, error amplifiers, and a 5.0 V reference. It supports master or slave operation for the oscillator and offers adjustable deadtime control.

 

Key electrical specifications include an operating voltage range of 7V to 40V, with a maximum power supply voltage of 42V. The output transistors are rated to 500 mA source or sink. The device operates at a frequency of 200 kHz and supports topologies such as Buck and Push-Pull. Control features include dead time control and frequency control.

 

The TL494CN is housed in a 16-PDIP package and is designed for through-hole mounting. Its operating ambient temperature range is 0°C to 70°C (TA). The part is suitable for applications requiring precise control over power supply output, such as in various power supply designs.
