Description and Introduction

BiCMOS Advanced Phase Shift PWM Controller The UCC3895DWTRG4 is a phase-shift PWM controller manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Texas Instruments (TI)  
- **Part Number:** UCC3895DWTRG4  
- **Package:** SOIC-20 (DW)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Supply Voltage (VDD):** 10V to 15V (max 20V)  
- **Output Current (Source/Sink):** 100mA (peak)  
- **Switching Frequency:** Up to 1MHz  
- **Control Method:** Phase-Shifted PWM  
- **Number of Outputs:** 4 (A, B, C, D)  

### **Descriptions:**
The UCC3895DWTRG4 is a high-performance phase-shift PWM controller designed for full-bridge power converter applications. It provides precise control over the phase shift between two half-bridge outputs, enabling efficient power conversion in resonant and hard-switched topologies.  

### **Features:**
- **Programmable Output Dead Time:** Adjustable delay between switching transitions.  
- **Adaptive Delay Set:** Enhances efficiency in ZVS (Zero Voltage Switching) applications.  
- **Voltage-Mode and Current-Mode Control:** Supports both control schemes.  
- **Soft-Start/Soft-Stop:** Reduces inrush current during startup.  
- **Synchronizable Oscillator:** Allows synchronization with external clocks.  
- **Error Amplifier:** Built-in for closed-loop control.  
- **Under-Voltage Lockout (UVLO):** Ensures proper operation within safe voltage ranges.  
- **Lead/Lag Phase Modulation:** Optimizes power delivery.  

This information is based solely on the manufacturer's datasheet. For detailed electrical characteristics and application notes, refer to the official TI documentation.
