Description and Introduction

Advanced Regulating Pulse Width Modulators The UC3524J is a pulse-width modulation (PWM) controller IC manufactured by Texas Instruments. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Texas Instruments  
- **Type:** PWM Controller  
- **Topology:** Push-Pull, Flyback, Forward  
- **Output Configuration:** Dual Inverting/Non-Inverting  
- **Output Current:** 100mA (sink/source per channel)  
- **Switching Frequency:** Up to 300kHz  
- **Supply Voltage (Vcc):** 8V to 40V  
- **Reference Voltage:** 5V (±1%)  
- **Duty Cycle Range:** 0% to 45% (adjustable)  
- **Operating Temperature Range:** -25°C to +85°C  
- **Package:** 16-Pin DIP (Dual In-Line Package)  

### **Descriptions:**
The UC3524J is a fixed-frequency PWM controller designed for DC-DC converter and power supply applications. It provides precise voltage regulation through adjustable duty cycle control and includes error amplifiers, a voltage reference, and oscillator circuitry.  

### **Features:**
- **Adjustable Dead-Time Control** – Prevents shoot-through in push-pull configurations.  
- **Error Amplifiers** – Two high-gain op-amps for feedback loop control.  
- **5V Precision Reference** – Stable voltage reference for regulation.  
- **Soft-Start Capability** – Reduces inrush current during startup.  
- **Current Limiting** – Protects against overload conditions.  
- **Synchronization Input** – Allows external clock synchronization.  
- **Under-Voltage Lockout (UVLO)** – Ensures proper operation at minimum supply voltage.  

This IC is commonly used in switch-mode power supplies (SMPS), inverters, and motor control circuits.
