Description and Introduction

High Performance Current Mode Controllers The UC3844DR2G is a high-performance current-mode PWM controller manufactured by ON Semiconductor.  

### **Specifications:**  
- **Topology:** Current-mode PWM controller  
- **Input Voltage Range:** 7.6V to 30V (operating), up to 36V (absolute max)  
- **Output Frequency:** Up to 500kHz  
- **Duty Cycle Range:** 0% to 100% (adjustable)  
- **Output Current (Peak):** ±1A (source/sink)  
- **Reference Voltage:** 5V (±1% accuracy)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOIC-8  

### **Descriptions:**  
The UC3844DR2G is designed for DC-DC converter applications, providing precise voltage regulation with current-mode control. It features an oscillator, error amplifier, current sensing comparator, and a totem-pole output stage for driving power MOSFETs.  

### **Features:**  
- **Current-Mode Operation:** Improves loop response and simplifies compensation.  
- **Undervoltage Lockout (UVLO):** Ensures proper startup and shutdown.  
- **Programmable Oscillator:** Allows frequency adjustment with external components.  
- **Pulse-by-Pulse Current Limiting:** Enhances system protection.  
- **Soft-Start Capability:** Reduces inrush current during startup.  
- **Low Startup Current:** Typically 0.5mA.  

This device is commonly used in switch-mode power supplies (SMPS), battery chargers, and flyback converters.
