Description and Introduction

Pulse-Width-Modulation (Pwm) Control Circuit The TL494CPW is a pulse-width modulation (PWM) control circuit manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Texas Instruments (TI)  
- **Package:** TSSOP-16  
- **Operating Temperature Range:** -40°C to +85°C  
- **Supply Voltage (VCC):** 7V to 40V  
- **Output Current (Sink/Source):** 200mA (per output)  
- **Switching Frequency:** Up to 300kHz  
- **Duty Cycle Range:** Adjustable from 0% to 100%  
- **Error Amplifier Bandwidth:** 3MHz (typical)  

### **Descriptions:**  
The TL494CPW is a fixed-frequency PWM controller designed for switch-mode power supply (SMPS) and DC-DC converter applications. It includes an on-chip oscillator, dead-time control, error amplifiers, and output drivers. The device is widely used in power regulation circuits due to its flexibility and reliability.  

### **Features:**  
- **Complete PWM Control Circuitry**  
- **Adjustable Dead-Time Control**  
- **On-Chip Error Amplifiers**  
- **Push-Pull or Single-Ended Output Configuration**  
- **Internal Oscillator with Synchronization Capability**  
- **Undervoltage Lockout (UVLO) Protection**  
- **Soft-Start Functionality via External Capacitor**  
- **Latching PWM for Cycle-by-Cycle Current Limiting**  

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