Description and Introduction

Advanced Regulating Pulse Width Modulators The UC2524J is a pulse-width modulation (PWM) controller manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Output Type:** PWM Controller  
- **Topology:** Buck, Boost, Flyback, Forward  
- **Frequency Range:** Up to 500 kHz  
- **Output Current:** 200 mA (sink/source)  
- **Supply Voltage (VCC):** 8V to 40V  
- **Duty Cycle Range:** 0% to 100%  
- **Operating Temperature Range:** -25°C to +85°C  
- **Package:** 16-pin DIP (Dual In-line Package)  

### **Descriptions:**
- The UC2524J is a fixed-frequency PWM controller designed for DC-DC converter applications.  
- It features an internal oscillator, error amplifier, and adjustable dead-time control.  
- Suitable for power supply designs requiring high efficiency and precise regulation.  

### **Features:**
- **Adjustable Frequency:** Set via external resistor and capacitor.  
- **Soft-Start Capability:** Reduces inrush current during startup.  
- **Current Limiting:** Provides protection against overloads.  
- **Error Amplifier:** Allows for feedback loop compensation.  
- **Synchronization Capability:** Can sync with an external clock.  
- **Under-Voltage Lockout (UVLO):** Ensures proper operation within voltage range.  

This information is based on TI's official documentation for the UC2524J.
