Description and Introduction

HIGH PERFORMANCE CURRENT MODE PWM CONTROLLER The UC3844AD1013TR is a current-mode PWM controller manufactured by STMicroelectronics (STM). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** STMicroelectronics (STM)  
- **Part Number:** UC3844AD1013TR  
- **Type:** Current-Mode PWM Controller  
- **Package:** SOIC-8  
- **Operating Temperature Range:** -40°C to +85°C  
- **Input Voltage (VCC):** Up to 30V  
- **Output Voltage:** Adjustable via external components  
- **Switching Frequency:** Up to 500kHz  
- **Duty Cycle Range:** 0% to 50% (internally clamped)  
- **Output Drive Current:** ±1A (peak)  
- **Reference Voltage:** 5V (±1% tolerance)  
- **UVLO (Undervoltage Lockout):** On: 16V (typical), Off: 10V (typical)  
- **Current Sense Input:** Adjustable current limit  

### **Descriptions:**  
The UC3844AD1013TR is a high-performance fixed-frequency current-mode PWM controller designed for DC-DC converter applications. It provides precise control of power converters with features like cycle-by-cycle current limiting, adjustable duty cycle, and under-voltage lockout (UVLO) protection.  

### **Features:**  
- **Current-Mode Control:** Improves loop response and simplifies compensation.  
- **Internal Trimmed Reference:** 5V with ±1% accuracy.  
- **Adjustable Frequency:** Up to 500kHz operation.  
- **High-Current Totem Pole Output:** Directly drives power MOSFETs.  
- **Undervoltage Lockout (UVLO):** Ensures proper startup and shutdown.  
- **Cycle-by-Cycle Current Limiting:** Enhances system reliability.  
- **Low Startup Current:** Typically 0.5mA.  
- **SOIC-8 Package:** Compact and suitable for space-constrained designs.  

This information is strictly based on the manufacturer's datasheet and technical documentation.
