Description and Introduction

BiCMOS Low Current 8 Pin PWM Current Mode Controller The UCC28C42DR is a high-performance current-mode PWM controller manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Output Configuration:** Push-Pull  
- **Topology:** Boost, Flyback, Forward  
- **Switching Frequency:** Up to 1 MHz  
- **Supply Voltage (VCC):** 8.5V to 16V (operating), 20V (max)  
- **Duty Cycle (Max):** 100%  
- **Output Current (Source/Sink):** 1A (peak)  
- **Operating Temperature Range:** -40°C to +105°C  
- **Package:** SOIC-8  

### **Descriptions:**  
The UCC28C42DR is designed for high-frequency, high-efficiency power supply applications. It features current-mode control for improved loop response and line regulation. The device includes under-voltage lockout (UVLO), cycle-by-cycle current limiting, and a totem-pole output stage for driving power MOSFETs.  

### **Features:**  
- **Current-Mode Control:** Enhances transient response and simplifies loop compensation.  
- **Programmable Switching Frequency:** Up to 1 MHz for compact designs.  
- **Under-Voltage Lockout (UVLO):** Ensures reliable operation under low input voltage conditions.  
- **Soft-Start Capability:** Reduces inrush current during startup.  
- **High-Current Totem-Pole Output:** Directly drives power MOSFETs.  
- **Cycle-by-Cycle Current Limiting:** Protects against overcurrent conditions.  
- **Low Startup Current:** Minimizes power consumption during standby.  

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