Description and Introduction

BiCMOS Advanced Phase Shift PWM Controller 20-SOIC 0 to 70 The UCC3895DWG4 is a phase-shift PWM controller manufactured by Texas Instruments (TI). Here are its key specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Texas Instruments (TI)  
- **Type:** Phase-Shift PWM Controller  
- **Package:** SOIC-20 (DWG4)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Supply Voltage (VDD):** 10V to 15V (max 20V)  
- **Output Current (Source/Sink):** 100mA (peak)  
- **Switching Frequency Range:** Up to 1MHz  
- **Control Method:** Voltage-Mode, Phase-Shifted Full-Bridge  
- **Duty Cycle Range:** 0% to 100%  

### **Descriptions:**
The UCC3895DWG4 is a high-performance phase-shift PWM controller designed for full-bridge power conversion applications. It provides precise control over the phase shift between two half-bridge outputs, enabling efficient power delivery with reduced switching losses.  

### **Features:**
- **Programmable Output Dead Time:** Adjustable delay between switching transitions.  
- **Adaptive Delay Set:** Enhances efficiency by minimizing body diode conduction.  
- **Soft-Start Function:** Reduces inrush current during startup.  
- **Synchronizable Oscillator:** Allows synchronization with an external clock.  
- **Error Amplifier:** Supports voltage-mode control with compensation.  
- **Under-Voltage Lockout (UVLO):** Ensures proper operation within supply limits.  
- **Current-Limiting Capability:** Protects against overload conditions.  

This device is commonly used in high-power DC-DC converters, telecom power supplies, and industrial applications.  

(Note: Always refer to the official datasheet for detailed electrical characteristics and application guidelines.)
