TL494CDR

The TL494CDR is a Pulse Width Modulation (PWM) controller produced by Texas Instruments, primarily used for designing switch-mode power supplies and DC-DC converters. Here are its main features and specifications:

1. Dual Output Control: Can be configured for single-ended or push-pull outputs.
2. Pulse Width Modulation (PWM): Provides precise control of the output pulse width to achieve stable voltage and current.
3. Oscillation Frequency: Wide frequency range, typically adjustable between 1 kHz and 300 kHz.
4. Dead Time Control: Adjustable to prevent overlap conduction of output transistors.
5. Error Amplifiers: Two built-in error amplifiers for precise adjustment of the output voltage.
6. 5V Reference Voltage Source: Provides a stable reference voltage to ensure the accuracy of PWM control.
7. Package: 8-pin SOIC (Small Outline Integrated Circuit).

These features make the TL494CDR widely used in power management systems, DC-DC converters, switch-mode power supplies, industrial controls, and battery chargers.
