Description and Introduction

SWITCHMODE TM Pulse Width Modulation Control Circuit The TL494CDR2 is a pulse-width modulation (PWM) controller IC manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Type:** PWM Controller  
- **Topology:** Buck, Boost, Flyback, Forward  
- **Output Type:** Dual (Push-Pull or Single-Ended)  
- **Frequency Range:** Up to 300 kHz  
- **Duty Cycle Max:** 45% (Push-Pull), 90% (Single-Ended)  
- **Supply Voltage (VCC):** 7V to 40V  
- **Output Current (Sink/Source):** 200mA  
- **Error Amplifier Bandwidth:** 3 MHz  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOIC-16  

### **Descriptions:**  
The TL494CDR2 is a fixed-frequency PWM controller with adjustable dead-time control, error amplifiers, and an on-chip oscillator. It is widely used in power supply applications, including DC-DC converters and inverters.  

### **Features:**  
- Adjustable dead-time control  
- Internal oscillator with sync capability  
- Dual error amplifiers  
- Uncommitted output transistors (200mA sink/source)  
- Under-voltage lockout (UVLO)  
- Soft-start control capability  

This information is based on TI's official datasheet for the TL494CDR2.
