Description and Introduction

BiCMOS Low-Power Current Mode PWM Controller The UCC28C41DGK is a high-performance current-mode PWM controller manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Texas Instruments (TI)  
- **Package:** VSSOP-8 (DGK)  
- **Topology:** Current-Mode PWM Controller  
- **Input Voltage Range (VCC):** 8.5V to 21V  
- **Operating Frequency Range:** Up to 1MHz  
- **Output Drive Current (Peak):** ±1A  
- **Duty Cycle Range:** 0% to 100%  
- **UVLO (Undervoltage Lockout):** 8V (on), 7.6V (off)  
- **Operating Temperature Range:** -40°C to +125°C  

### **Descriptions:**  
The UCC28C41DGK is a high-speed, low-power current-mode PWM controller designed for offline and DC-DC power supplies. It provides precise regulation with features like adjustable frequency, soft-start, and cycle-by-cycle current limiting. The device is optimized for high-efficiency power conversion applications.  

### **Features:**  
- **Current-Mode Control:** Improves loop response and simplifies compensation.  
- **Adjustable Switching Frequency:** Up to 1MHz for flexible design.  
- **Programmable Soft-Start:** Reduces inrush current during startup.  
- **Cycle-by-Cycle Current Limiting:** Enhances system protection.  
- **Low Startup Current (150µA typical):** Improves efficiency in standby mode.  
- **Internal Leading-Edge Blanking:** Reduces noise sensitivity in current sensing.  
- **Totem-Pole Output:** Supports high-side and low-side MOSFET driving.  
- **Wide Operating Temperature Range:** Suitable for industrial applications.  

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