Description and Introduction

BiCMOS Advanced Phase Shift PWM Controller The UCC3895PW is a phase-shift PWM controller manufactured by Texas Instruments (TI)/Burr-Brown (BB). Below are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Supply Voltage (VDD):** 10V to 15V (operating range)  
- **Output Current (Source/Sink):** 100mA (peak)  
- **Switching Frequency Range:** Up to 1MHz  
- **Duty Cycle Range:** 0% to 100%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 20-pin TSSOP (PW)  

### **Descriptions:**  
- The UCC3895PW is a high-performance phase-shift PWM controller designed for full-bridge or half-bridge power converters.  
- It provides adaptive delay control for zero-voltage switching (ZVS) in resonant and clamped-mode power supplies.  
- Features programmable output turn-on delays and dead-time control for improved efficiency.  

### **Features:**  
- **Adaptive Delay Set:** Adjusts dead time dynamically for optimal ZVS.  
- **Programmable Oscillator:** Allows frequency adjustment via external components.  
- **Soft-Start/Soft-Stop:** Reduces inrush current during startup/shutdown.  
- **Error Amplifier:** Includes a high-gain transconductance amplifier for feedback control.  
- **Synchronization Capability:** Supports master/slave operation for multi-phase systems.  
- **Under-Voltage Lockout (UVLO):** Ensures proper operation within voltage limits.  
- **Current-Limit Protection:** Enhances system reliability.  

This information is based solely on the manufacturer's datasheet for the UCC3895PW.
