Description and Introduction

BiCMOS Low-Power Current Mode PWM Controller The UCC28C40DGKR is a high-performance current-mode PWM controller manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Topology:** Current-mode PWM controller  
- **Input Voltage Range:** 8.4V to 18V (VDD)  
- **Operating Frequency:** Up to 1MHz (adjustable)  
- **Output Duty Cycle:** Up to 50% (for push-pull applications)  
- **Peak Output Current:** ±1A (source/sink)  
- **Soft-Start Capability:** Yes  
- **Undervoltage Lockout (UVLO):** Adjustable  
- **Error Amplifier Bandwidth:** 5MHz  
- **Package:** 8-pin VSSOP (DGK)  

### **Descriptions:**  
The UCC28C40DGKR is designed for high-frequency power supply applications, offering precise control with current-mode operation. It includes features like soft-start, cycle-by-cycle current limiting, and adjustable UVLO for robust system protection.  

### **Features:**  
- **Current-Mode Control:** Improves transient response and simplifies loop compensation.  
- **Adjustable Switching Frequency:** Allows optimization for efficiency and component size.  
- **High-Current Totem Pole Outputs:** Drive power MOSFETs efficiently.  
- **Programmable Soft-Start:** Reduces inrush current during startup.  
- **UVLO with Hysteresis:** Ensures reliable operation under varying supply conditions.  
- **Low Start-Up Current:** Reduces power consumption during standby.  

For detailed electrical characteristics and application circuits, refer to the official TI datasheet.
