Description and Introduction

Pulse-Width-Modulation (PWM) Control Circuit The TL594INSR is a pulse-width modulation (PWM) control circuit manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Output Type:** Push-Pull  
- **Topology:** Buck, Boost, Flyback, Forward  
- **Switching Frequency:** Up to 300 kHz  
- **Supply Voltage (VCC):** 7V to 40V  
- **Output Current (Source/Sink):** 200mA (max)  
- **Duty Cycle Range:** 0% to 45% (adjustable)  
- **Error Amplifier Bandwidth:** 1 MHz (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOIC-16  

### **Descriptions:**  
The TL594INSR is a fixed-frequency PWM controller designed for DC-DC converter and power supply applications. It features an internal oscillator, error amplifiers, a dead-time control comparator, and an output control circuit. It is commonly used in switch-mode power supplies (SMPS), inverters, and motor control systems.  

### **Features:**  
- **Complete PWM Control Circuitry**  
- **On-Chip Error Amplifiers**  
- **Adjustable Dead-Time Control**  
- **Internal Oscillator with Sync Capability**  
- **Undervoltage Lockout (UVLO) Protection**  
- **Output Control for Push-Pull or Single-Ended Operation**  
- **Soft-Start Functionality**  

This device is RoHS compliant and lead-free.
