Description and Introduction

SWITCHMODE TM Pulse Width Modulation Control Circuit The TL494BDR2G is a pulse-width modulation (PWM) controller IC manufactured by ON Semiconductor.  

### **Specifications:**  
- **Type:** PWM Controller  
- **Topology:** Buck, Boost, Flyback, Forward  
- **Output Type:** Dual Source/Sink  
- **Frequency Range:** Up to 300 kHz  
- **Duty Cycle Max:** 45% (each output)  
- **Supply Voltage (VCC):** 7V to 40V  
- **Output Current:** 200mA (sink/source per output)  
- **Operating Temperature Range:** -40°C to +105°C  
- **Package:** SOIC-16 (Surface Mount)  

### **Descriptions:**  
The TL494BDR2G is a fixed-frequency PWM control circuit with adjustable dead-time control, error amplifiers, and an on-chip oscillator. It is designed for switch-mode power supply (SMPS) applications.  

### **Features:**  
- Complete PWM control circuitry  
- Adjustable dead-time control  
- Internal error amplifiers  
- On-chip oscillator with sync capability  
- Uncommitted output transistors (200mA sink/source)  
- Under-voltage lockout (UVLO)  
- Dual alternating outputs for push-pull or single-ended operation  

This device is commonly used in DC-DC converters, inverters, and power supply control applications.
