Description and Introduction

Low-Power BiCMOS Current-Mode PWM The UCC3805PW is a high-performance current-mode PWM controller manufactured by Texas Instruments (BB/TI). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Texas Instruments (BB/TI)  
- **Part Number:** UCC3805PW  
- **Package:** 8-Pin TSSOP (PW)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Supply Voltage (VCC):** Up to 12V  
- **Output Drive Current:** ±1A (peak)

- **Propagation Delay:** 50ns (typical)  

### **Descriptions:**  
The UCC3805PW is a BiCMOS current-mode PWM controller optimized for high-frequency DC-DC converter applications. It provides precise control for power supplies with features like cycle-by-cycle current limiting, soft-start, and under-voltage lockout (UVLO).  

### **Features:**  
- **Current-Mode Control:** Enhances transient response and simplifies loop compensation.  
- **High-Speed Operation:** Supports switching frequencies up to 1MHz.  
- **Low Start-Up Current:** Enables efficient power-up sequences.  
- **Programmable Soft-Start:** Reduces inrush current during startup.  
- **Under-Voltage Lockout (UVLO):** Ensures proper operation within voltage limits.  
- **Cycle-by-Cycle Current Limiting:** Protects against overcurrent conditions.  
- **BiCMOS Technology:** Low power consumption and high-speed performance.  
- **Wide Duty Cycle Range:** Supports 0% to 100% operation.  

This information is strictly based on the manufacturer's datasheet and specifications.
