Description and Introduction

Pulse-Width-Modulation (Pwm) Control Circuit The TL494CNSR is a pulse-width modulation (PWM) controller IC manufactured by Texas Instruments (TI) and Burr-Brown (BB).  

### **Specifications:**  
- **Type:** PWM Controller  
- **Topology:** Push-Pull, Half-Bridge, Full-Bridge  
- **Frequency Range:** Up to 300 kHz  
- **Output Current:** 200 mA (sink/source per output)  
- **Supply Voltage (VCC):** 7V to 40V  
- **Duty Cycle Range:** 0% to 45% (adjustable)  
- **Error Amplifier Bandwidth:** 3 MHz  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOIC-16 (Surface Mount)  

### **Descriptions:**  
The TL494CNSR is a fixed-frequency PWM control circuit with adjustable dead-time control, an on-chip oscillator, and error amplifiers. It is commonly used in switch-mode power supplies (SMPS), DC-DC converters, and motor control applications.  

### **Features:**  
- Adjustable dead-time control  
- On-chip oscillator with sync capability  
- Uncommitted error amplifiers  
- Internal 5V reference (±1% accuracy)  
- Push-pull or single-ended output configuration  
- Undervoltage lockout (UVLO)  
- Soft-start capability  

This IC is designed for precision control in power conversion applications.
