Description and Introduction

HIGH PERFORMANCE CURRENT MODE PWM CONTROLLER The **UC2844AD1013TR** is a high-performance current-mode PWM controller manufactured by **STMicroelectronics (ST)**. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Manufacturer:**  
STMicroelectronics (ST)  

### **Description:**  
The **UC2844AD1013TR** is a fixed-frequency pulse-width modulation (PWM) controller designed for DC-DC converter and power supply applications. It operates in **current-mode control**, providing precise regulation and improved loop response.  

### **Key Features:**  
- **Operating Frequency:** Up to **500 kHz**  
- **Current-Mode Control:** Enhances line and load regulation  
- **Adjustable Duty Cycle:** Up to **50%** (for push-pull configurations)  
- **Under-Voltage Lockout (UVLO):** Ensures proper start-up with **8.4V (on) / 7.6V (off)** thresholds  
- **High-Current Totem Pole Output:** **±1A** peak drive capability  
- **Low Startup Current:** **< 1mA**  
- **Error Amplifier:** Wide bandwidth for fast response  
- **Soft-Start Capability:** Reduces inrush current  
- **Latching PWM:** Prevents multiple pulses per cycle  
- **Package Type:** **SOIC-8**  

### **Applications:**  
- Switch-mode power supplies (SMPS)  
- DC-DC converters  
- Offline power supplies  
- Battery chargers  

This information is strictly based on the manufacturer's datasheet and technical documentation. No additional suggestions or guidance are included.
