Description and Introduction

Low-Power BiCMOS Current-Mode PWM The UCC2805QDREP is a high-speed, low-power BiCMOS current-mode PWM controller manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Topology:** Current-mode PWM controller  
- **Input Voltage Range:** 7V to 12V (operating)  
- **Switching Frequency:** Up to 1MHz  
- **Output Drive Current:** ±1A (peak)  
- **Duty Cycle Range:** 0% to 100%  
- **Operating Temperature Range:** -40°C to +105°C  
- **Package:** SOIC-8 (D)  

### **Descriptions:**  
The UCC2805QDREP is designed for high-efficiency power supply applications, featuring fast response and precise current-mode control. It includes protections such as undervoltage lockout (UVLO), cycle-by-cycle current limiting, and a built-in soft-start function.  

### **Features:**  
- **Current-Mode Control:** Enhances transient response and simplifies loop compensation.  
- **Low Startup Current:** Typically 0.5mA.  
- **Adjustable Switching Frequency:** Up to 1MHz.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation within voltage range.  
- **Soft-Start Capability:** Reduces inrush current.  
- **High-Current Totem Pole Output:** Suitable for driving power MOSFETs.  

This device is optimized for applications such as DC-DC converters, power supplies, and battery chargers.
