TL494CDR2G Description

Short technical summary and product information.

The TL494CDR2G is a fixed-frequency, pulse width modulation (PWM) control circuit from On Semiconductor, primarily designed for switch mode power supply applications. It features on-chip oscillator, error amplifiers, and a 5.0 V reference. The device supports both push-pull and single-ended operation, with adjustable deadtime control.

 

Key electrical specifications include a wide operating supply voltage range of 7V to 40V, with a maximum collector output voltage of 42V. The output transistors are rated for up to 500 mA source or sink current. The operating frequency can reach up to 200 kHz, and it supports topologies such as Buck and Push-Pull.

 

This component is housed in a 16-SOIC package and is designed for surface mount applications. The operating ambient temperature range is 0°C to 70°C (TA). It is specified with RoHS3 compliance and an MSL of 1.

 

The TL494CDR2G is suitable for various power supply designs requiring precise control over switching parameters.
