Description and Introduction

BiCMOS Low-Power Current Mode PWM Controller The UCC28C41DR is a high-performance current-mode PWM controller manufactured by Texas Instruments (TI). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Manufacturer:**  
Texas Instruments (TI)  

### **Part Number:**  
UCC28C41DR  

### **Description:**  
The UCC28C41DR is a current-mode pulse-width modulation (PWM) controller designed for offline and DC-DC power supply applications. It provides precise duty cycle control with high noise immunity and low power consumption.  

### **Key Features:**  
- **Current-Mode Control:** Enhances loop response and simplifies compensation.  
- **Adjustable Switching Frequency:** Up to 1 MHz.  
- **Low Startup Current:** Typically 0.5 mA.  
- **Under-Voltage Lockout (UVLO):** Ensures proper operation under low input voltage conditions.  
- **Soft-Start Capability:** Reduces inrush current during startup.  
- **High-Current Totem Pole Output:** 1A peak output current for driving power MOSFETs.  
- **Error Amplifier with Precise Reference:** 5V ±1% internal reference voltage.  
- **Leading-Edge Blanking:** Improves noise immunity in current sensing.  
- **Synchronization Capability:** Allows external clock synchronization.  
- **Wide Operating Voltage Range:** 8.4V to 35V.  

### **Package:**  
- **SOIC-8 (DR Package)**  

### **Applications:**  
- AC/DC power supplies  
- DC-DC converters  
- Flyback and forward converters  
- Industrial and telecom power systems  

This information is based solely on the manufacturer's datasheet and specifications.
