Description and Introduction

BiCMOS Advanced Phase Shift PWM Controller The UCC3895DW is a phase-shift PWM controller manufactured by Texas Instruments. Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Texas Instruments  
- **Package:** SOIC-20 (DW)  
- **Type:** Phase-Shift PWM Controller  
- **Operating Voltage Range:** 4.5V to 12V  
- **Output Current (Source/Sink):** 100mA (max)  
- **Switching Frequency Range:** Up to 1MHz  
- **Duty Cycle Range:** 0% to 100%  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
- The UCC3895DW is a high-performance phase-shift PWM controller designed for full-bridge or half-bridge power conversion applications.  
- It provides adaptive delay control to ensure zero-voltage switching (ZVS) in resonant power supplies.  
- The device includes programmable output turn-on delays, enabling efficient power stage operation.  

### **Features:**  
- **Adaptive Delay Control:** Optimizes efficiency by adjusting dead time for ZVS.  
- **Programmable Output Turn-On Delays:** Allows precise timing adjustments.  
- **Bidirectional Oscillator Synchronization:** Supports master or slave operation.  
- **Soft-Start and Soft-Stop Capability:** Reduces inrush current and voltage stress.  
- **Error Amplifier with Reference:** Provides closed-loop control for voltage regulation.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation within voltage limits.  
- **Current-Limit Protection:** Safeguards against overcurrent conditions.  

This information is strictly based on the manufacturer's datasheet and technical documentation. No additional guidance or suggestions are included.
