TL494BDR2G Description

Short technical summary and product information.

The TL494BDR2G from ON Semiconductor is a fixed-frequency pulse width modulation (PWM) control circuit. It is primarily designed for controlling switch mode power supplies. This device integrates a complete PWM control circuitry, including an on-chip oscillator, error amplifiers, and a 5.0 V reference.

 

Key electrical specifications include an operating voltage range of 7V to 40V, a maximum duty cycle of 48%, and a switching frequency of 200kHz. The output transistors are rated for 500 mA source or sink current. It supports both push-pull and single-ended operation and features adjustable deadtime control.

 

The TL494BDR2G is available in a 16-SOIC surface mount package. It operates within an ambient temperature range of -40°C to +125°C. This component is suitable for applications requiring precise control over power supply output.

 

This device offers features such as undervoltage lockout and an on-chip oscillator that supports master or slave operation. The output control is designed for flexibility in various power supply configurations.
