Description and Introduction

Low-Power BiCMOS Current-Mode PWM 8-SOIC -40 to 85 The UCC2805DTRG4 is a high-speed, low-power BiCMOS current-mode PWM controller manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Topology:** Current-mode PWM controller  
- **Input Voltage (VCC):** 10V to 20V (operating range)  
- **Switching Frequency:** Up to 1MHz  
- **Output Drive Current:** ±1A (peak)  
- **Duty Cycle Range:** 0% to 100%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOIC-8 (D)  

### **Descriptions:**  
The UCC2805DTRG4 is designed for high-performance power supply applications, providing precise current-mode control with fast transient response. It includes features like under-voltage lockout (UVLO), cycle-by-cycle current limiting, and soft-start functionality.  

### **Features:**  
- **Current-Mode Control:** Improves loop response and simplifies compensation.  
- **BiCMOS Technology:** Ensures low power consumption and high-speed operation.  
- **Programmable Soft-Start:** Reduces inrush current during startup.  
- **Under-Voltage Lockout (UVLO):** Ensures proper operation within the specified voltage range.  
- **High-Frequency Operation:** Supports switching frequencies up to 1MHz.  
- **Low Startup Current:** Typically 0.5mA.  
- **Internal Trimmed Reference:** Ensures accurate voltage regulation.  

This device is commonly used in DC-DC converters, offline power supplies, and other power management applications.
