Description and Introduction

HIGH PERFORMANCE CURRENT MODE PWM CONTROLLER The UC2843AD1013TR is a PWM controller IC manufactured by STMicroelectronics. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** STMicroelectronics  
- **Part Number:** UC2843AD1013TR  
- **Type:** Current Mode PWM Controller  
- **Package:** SOIC-8  
- **Operating Temperature Range:** -40°C to +85°C  
- **Input Voltage (VCC):** Up to 30V  
- **Output Drive Current:** ±1A (Peak)  
- **Switching Frequency:** Up to 500kHz  
- **Duty Cycle Range:** 0% to 100%  
- **Reference Voltage:** 5V (±1%)  
- **UVLO (Under-Voltage Lockout):** 8.4V (on) / 7.6V (off)  

### **Descriptions:**  
The UC2843AD1013TR is a high-performance current-mode PWM controller designed for DC-DC converter and power supply applications. It provides precise regulation with features like adjustable frequency, soft-start, and cycle-by-cycle current limiting.  

### **Features:**  
- **Current-Mode Control:** Improves loop response and simplifies compensation.  
- **Automatic Feed-Forward Compensation:** Enhances line regulation.  
- **Latching PWM for Cycle-by-Cycle Current Limiting:** Protects against overloads.  
- **Internal Trimmed Bandgap Reference:** Ensures stable 5V output.  
- **High-Current Totem Pole Output:** Directly drives power MOSFETs.  
- **Low Startup and Operating Current:** Suitable for low-power applications.  
- **Undervoltage Lockout (UVLO):** Ensures proper startup and shutdown.  

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