Description and Introduction

SWITCHMODE TM Pulse Width Modulation Control Circuit The TL494CNG from ON Semiconductor is a pulse-width-modulation (PWM) control circuit with the following specifications and features:  

### **Manufacturer:** ON Semiconductor  
### **Pb-Free Specifications:**  
- The TL494CNG is **lead-free (Pb-free)** and complies with RoHS (Restriction of Hazardous Substances) standards.  

### **Descriptions:**  
- The TL494CNG is a fixed-frequency PWM control circuit designed for switch-mode power supply applications.  
- It incorporates all the necessary functions for building a PWM control circuit, including an on-chip oscillator, error amplifiers, a dead-time control comparator, and output control logic.  
- It operates over a wide voltage range (7V to 40V) and is suitable for push-pull or single-ended output configurations.  

### **Features:**  
- **Complete PWM Control Circuitry**  
- **Adjustable Dead-Time Control**  
- **On-Chip Oscillator with Master or Slave Operation**  
- **Internal Error Amplifiers**  
- **Output Control for Push-Pull or Single-Ended Operation**  
- **Undervoltage Lockout (UVLO)**  
- **Operating Voltage Range:** 7V to 40V  
- **Output Sink/Source Current:** 200mA (max)  
- **Pb-Free and RoHS Compliant**  

This information is strictly based on the manufacturer's datasheet and specifications.
