Description and Introduction

Pulse-Width-Modulation (Pwm) Control Circuit The TL494CDR is a pulse-width modulation (PWM) control circuit manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features:

### **Specifications:**  
- **Manufacturer:** Texas Instruments (TI)  
- **Part Number:** TL494CDR  
- **Type:** PWM Controller IC  
- **Package:** SOIC-16  
- **Operating Voltage Range:** 7V to 40V  
- **Output Current:** 200mA (sink/source per output)  
- **Frequency Range:** Up to 300kHz  
- **Duty Cycle Range:** Adjustable from 0% to 100%  
- **Number of Outputs:** 2 (push-pull or single-ended)  
- **Error Amplifier Bandwidth:** 3MHz (typical)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The TL494CDR is a fixed-frequency PWM control circuit designed for power supply and DC-DC converter applications. It includes an on-chip oscillator, error amplifiers, a dead-time control comparator, and output control logic. The device can be configured for push-pull or single-ended operation.

### **Features:**  
- Adjustable dead-time control  
- Internal oscillator with sync capability  
- Dual error amplifiers for feedback control  
- Under-voltage lockout (UVLO) protection  
- Soft-start capability  
- Output control for push-pull or single-ended operation  
- High output drive current (200mA per output)  
- Wide operating voltage range (7V to 40V)  

This information is based on the manufacturer's datasheet. For detailed application notes, refer to TI's official documentation.
