Description and Introduction

Current Mode Push-Pull PWM With Programmable Slope Compensation 8-SOIC 0 to 70 The UCC38084DG4 is a high-performance current-mode PWM controller manufactured by Texas Instruments (TI)/Burr-Brown (BB). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:  

### **Specifications:**  
- **Manufacturer:** Texas Instruments (TI)/Burr-Brown (BB)  
- **Type:** Current-Mode PWM Controller  
- **Topology:** Flyback, Forward, Boost, Buck  
- **Output Configuration:** Single  
- **Number of Outputs:** 1  
- **Switching Frequency:** Up to 1MHz  
- **Duty Cycle (Max):** 90%  
- **Supply Voltage (Vcc):** 10V to 18V (Operating)  
- **UVLO (Undervoltage Lockout):** 8.5V (Turn-On), 7.6V (Turn-Off)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOIC-8  

### **Descriptions:**  
The UCC38084DG4 is a high-speed, low-power current-mode PWM controller optimized for offline and DC-DC power supplies. It features a precision reference, oscillator, error amplifier, and current-sensing comparator for accurate regulation.  

### **Features:**  
- **Current-Mode Control:** Provides improved transient response and simplified loop compensation.  
- **High-Speed Operation:** Supports switching frequencies up to 1MHz.  
- **Low Startup and Operating Current:** Reduces power consumption.  
- **Internal Soft-Start:** Minimizes inrush current during startup.  
- **Cycle-by-Cycle Current Limiting:** Enhances system protection.  
- **Leading-Edge Blanking:** Improves noise immunity in current sensing.  
- **Under-Voltage Lockout (UVLO):** Ensures proper operation within voltage range.  
- **Totem-Pole Output:** Capable of driving MOSFETs directly.  

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