Description and Introduction

BiCMOS Low-Power Current Mode PWM Controller The UCC38C42D is a high-performance current-mode PWM controller manufactured by Texas Instruments (TI) / Unitrode.  

### **Specifications:**  
- **Input Voltage Range:** 10V to 20V (operating)  
- **Maximum Duty Cycle:** 100%  
- **Switching Frequency:** Up to 1MHz  
- **Output Drive Current:** ±1A (peak)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOIC-8  

### **Descriptions and Features:**  
- **Current-Mode Control:** Provides improved transient response and simplified loop compensation.  
- **Programmable Switching Frequency:** Allows flexibility in design.  
- **Under-Voltage Lockout (UVLO):** Ensures proper start-up and shutdown.  
- **Soft-Start Capability:** Reduces inrush current during startup.  
- **Low Startup Current:** Typically 0.5mA.  
- **Error Amplifier:** Features wide bandwidth for fast response.  
- **Leading-Edge Blanking:** Improves noise immunity in current sensing.  
- **Synchronization Capability:** Can be synchronized to an external clock.  

This PWM controller is commonly used in DC-DC converters, power supplies, and other switching regulator applications.
