Description and Introduction

Advanced Regulating Pulse Width Modulators The UC2524AJ is a pulse width modulation (PWM) controller manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Texas Instruments (TI)  
- **Part Number:** UC2524AJ  
- **Type:** PWM Controller  
- **Topology:** Buck, Boost, Flyback, Forward  
- **Output Type:** Dual, Complementary  
- **Output Current:** 100mA (sink/source per channel)  
- **Switching Frequency:** Up to 500kHz  
- **Input Voltage Range:** 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 (Plastic)  

### **Descriptions:**  
The UC2524AJ is a fixed-frequency pulse width modulation (PWM) controller designed for DC-DC converter and power supply applications. It provides precise voltage regulation and includes features such as adjustable duty cycle, soft-start capability, and error amplification.  

### **Features:**  
- **Dual Output Drivers:** Push-pull configuration for driving power MOSFETs or transistors.  
- **Adjustable Frequency:** External resistor and capacitor set switching frequency.  
- **Error Amplifier:** Onboard op-amp for feedback loop control.  
- **Soft-Start:** Reduces inrush current during startup.  
- **Current Limiting:** Protects against overload conditions.  
- **Under-Voltage Lockout (UVLO):** Ensures proper operation within voltage range.  
- **Dead-Time Control:** Adjustable to prevent shoot-through in half-bridge or full-bridge topologies.  

This information is based solely on the technical specifications provided by Texas Instruments for the UC2524AJ PWM controller.
