Description and Introduction

HIGH PERFORMANCE CURRENT MODE PWM CONTROLLER The UC3844BD1013TR is a high-performance current-mode PWM controller manufactured by STMicroelectronics.  

### **Specifications:**  
- **Manufacturer:** STMicroelectronics  
- **Type:** Current-Mode PWM Controller  
- **Topology:** Flyback, Forward, Boost, Buck  
- **Operating Frequency:** Up to 500 kHz  
- **Output Drive Current:** 1A (peak)  
- **Supply Voltage (VCC):** 8.5V to 30V  
- **UVLO (Undervoltage Lockout):** On-Chip (8.4V Turn-On, 7.6V Turn-Off)  
- **Duty Cycle:** 0% to 50% (adjustable)  
- **Package:** SO-8  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The UC3844BD1013TR is designed for DC-DC converter applications, providing precise control for switching power supplies. It features a fixed-frequency current-mode architecture, ensuring stable operation with minimal external components.  

### **Features:**  
- **Current-Mode Control:** Improves loop response and simplifies compensation.  
- **Latching PWM:** Ensures single-pulse operation per cycle.  
- **Internal Trimmed Reference:** 5V ±1% tolerance.  
- **Soft-Start Capability:** Reduces inrush current.  
- **Low Startup Current:** Typically 0.5mA.  
- **High-Current Totem Pole Output:** Directly drives power MOSFETs.  
- **Cycle-by-Cycle Current Limiting:** Enhances protection.  

This device is commonly used in offline and DC-DC power supplies, battery chargers, and industrial applications.
