Description and Introduction

BiCMOS Low-Power Current Mode PWM Controller The UCC38C42DR is a high-performance current-mode PWM controller manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 30V  
- **Operating Frequency Range:** Up to 1MHz  
- **Output Duty Cycle Range:** 0% to 100%  
- **Maximum Output Current (Source/Sink):** 1A  
- **Reference Voltage:** 5V (±1%)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOIC-8  

### **Descriptions:**  
The UCC38C42DR is a versatile PWM controller designed for high-frequency switching power supplies. It operates in current-mode control, providing improved transient response and simplified loop compensation. It is suitable for applications like DC-DC converters, offline power supplies, and battery chargers.  

### **Features:**  
- **Current-Mode Control:** Enhances loop stability and transient response.  
- **Programmable Oscillator:** Allows frequency adjustment with external components.  
- **Soft-Start Function:** Reduces inrush current during startup.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation within voltage range.  
- **Leading-Edge Blanking:** Improves noise immunity in current sensing.  
- **Low Startup Current:** Typically 150µA for efficient operation.  
- **Synchronization Capability:** Can sync with external clock signals.  

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