Description and Introduction

Current Mode Push-Pull PWM With Programmable Slope Compensation The UCC38085D is a high-performance current-mode PWM controller manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Topology:** Current-mode PWM controller  
- **Input Voltage Range:** 8.5V to 21V (operating)  
- **UVLO (Undervoltage Lockout):** 8.5V (on), 7.6V (off)  
- **Switching Frequency:** Up to 1MHz  
- **Output Drive Current:** ±1.5A (peak)  
- **Duty Cycle Range:** 0% to 100%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOIC-8  

### **Descriptions:**  
The UCC38085D is designed for high-efficiency power supply applications, providing precise control for DC-DC converters. It features cycle-by-cycle current limiting, soft-start, and adjustable frequency operation.  

### **Features:**  
- **Current-Mode Control:** Enhances transient response and simplifies loop compensation.  
- **Programmable Soft-Start:** Reduces inrush current during startup.  
- **Internal Leading-Edge Blanking:** Improves noise immunity.  
- **Synchronization Capability:** Allows external clock synchronization.  
- **Low Startup Current:** Typically 150µA.  
- **Overcurrent Protection:** Cycle-by-cycle current limiting.  
- **High-Speed Gate Drive:** Optimized for MOSFET switching.  

This information is based on TI's official datasheet for the UCC38085D.
