Description and Introduction

BiCMOS Low Current 8 Pin PWM Current Mode Controller The UCC28C42DGK is a high-performance current-mode PWM controller manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Topology:** Current-mode PWM controller  
- **Input Voltage Range (VDD):** 8.5V to 18V (operating), up to 30V (absolute max)  
- **Output Drive Current:** ±1A (peak)  
- **Switching Frequency:** Up to 1MHz  
- **Duty Cycle Range:** 0% to 100%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 8-Pin VSSOP (DGK)  

### **Descriptions:**  
The UCC28C42DGK is designed for high-frequency switching power supplies, providing precise regulation and protection features. It integrates a high-speed oscillator, error amplifier, and current-sensing comparator for efficient power conversion.  

### **Features:**  
- **Current-Mode Control:** Enhances loop response and simplifies compensation.  
- **Programmable Switching Frequency:** Adjustable via external components.  
- **Undervoltage Lockout (UVLO):** Ensures reliable startup and shutdown.  
- **Soft-Start Capability:** Reduces inrush current during startup.  
- **Leading-Edge Blanking:** Improves noise immunity in current sensing.  
- **Low Startup Current:** Typically 150µA for reduced standby power.  
- **High-Speed PWM Comparator:** Enables fast transient response.  

This device is commonly used in AC/DC converters, DC/DC power supplies, and industrial power systems.
