Description and Introduction

Advanced Regulating Pulse Width Modulators The UC1524 is a pulse width modulation (PWM) controller IC manufactured by Texas Instruments and other semiconductor companies. Below are the factual specifications, descriptions, and features of the UC1524:

### **Specifications:**  
- **Input Voltage Range:** 8V to 40V  
- **Output Current:** Up to 100mA (per output)  
- **Switching Frequency:** Adjustable up to 300kHz  
- **Duty Cycle Range:** 0% to 90%  
- **Reference Voltage Output:** 5V (±1%)  
- **Operating Temperature Range:** -55°C to +125°C  
- **Package Options:** DIP-16, SOIC-16  

### **Descriptions:**  
- The UC1524 is a fixed-frequency PWM controller designed for DC-DC converter and power supply applications.  
- It includes an on-board oscillator, error amplifier, voltage reference, and dual alternating output drivers.  
- The device is commonly used in push-pull, flyback, and buck/boost converter topologies.  

### **Features:**  
- **Adjustable Frequency:** External resistor and capacitor allow frequency tuning.  
- **Dual Output Drivers:** Provides alternating outputs for push-pull or single-ended operation.  
- **Current Limiting:** Built-in current sensing and limiting.  
- **Soft-Start Capability:** Reduces inrush current during startup.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation only above a minimum voltage threshold.  
- **Error Amplifier:** Allows closed-loop feedback control for voltage regulation.  

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