Description and Introduction

PULSE-WIDTH-MODULATION CONTROL CIRCUITS The TL493CN is a pulse-width modulation (PWM) control circuit manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Texas Instruments (TI)  
- **Type:** PWM Controller IC  
- **Package:** PDIP-16 (Plastic Dual In-line Package)  
- **Operating Voltage Range:** 7V to 40V  
- **Output Current (Sink/Source):** 200mA (per output)  
- **Frequency Range:** Adjustable (typically up to 300kHz)  
- **Duty Cycle Range:** 0% to 100%  
- **Error Amplifier Gain Bandwidth:** 1MHz (typical)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**
- The TL493CN is a fixed-frequency PWM control circuit designed for power supply and DC-DC converter applications.  
- It includes an on-board oscillator, error amplifier, dead-time control comparator, and dual alternating output drivers.  
- Suitable for push-pull, half-bridge, or single-ended power supply designs.  

### **Features:**
- **Complete PWM Control:** Includes all necessary functions for PWM regulation.  
- **Adjustable Dead-Time Control:** Prevents shoot-through in push-pull configurations.  
- **Internal Error Amplifier:** Provides feedback loop stability.  
- **Dual Output Drivers:** Supports totem-pole or common-emitter configurations.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation above 7V.  
- **Soft-Start Capability:** Reduces inrush current during startup.
