Description and Introduction

BiCMOS Low-Power Current Mode PWM Controller The UCC28C43DGKR is a high-performance current-mode PWM controller manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Topology:** Current-mode PWM controller  
- **Input Voltage Range (VCC):** 8.5V to 18V (operating), 20V (max)  
- **Output Drive Current:** ±1A (peak)  
- **Switching Frequency:** Up to 1MHz  
- **Duty Cycle Range:** 0% to 100%  
- **Error Amplifier Bandwidth:** 5MHz  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 8-pin VSSOP (DGK)  

### **Descriptions:**  
The UCC28C43DGKR is designed for high-frequency power supply applications, offering precise control with current-mode operation. It includes features like cycle-by-cycle current limiting, soft-start control, and undervoltage lockout (UVLO) for robust performance.  

### **Features:**  
- **Current-Mode Control:** Enhances transient response and simplifies loop compensation.  
- **Programmable Switching Frequency:** Adjustable up to 1MHz.  
- **Cycle-by-Cycle Current Limiting:** Protects against overcurrent conditions.  
- **Undervoltage Lockout (UVLO):** Ensures proper startup and shutdown.  
- **Soft-Start Capability:** Reduces inrush current during startup.  
- **High-Speed Error Amplifier:** Improves dynamic response.  
- **Low Startup Current:** Typically 0.5mA.  

This device is suitable for applications such as AC/DC converters, isolated power supplies, and DC/DC converters.
