Description and Introduction

Phase Shift Resonant Controller The UC3875DWPTR is a Phase Shift Resonant Controller manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Manufacturer:** Texas Instruments (TI)  
- **Part Number:** UC3875DWPTR  
- **Package:** SOIC-20 (DW)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Supply Voltage (VCC):** Up to 20V  
- **Output Current:** 2A peak  
- **Switching Frequency:** Programmable up to 2MHz  
- **Control Method:** Phase-shifted PWM  
- **Features:**  
  - Zero-voltage switching (ZVS) capability  
  - Adjustable dead time for resonant transitions  
  - Programmable oscillator frequency  
  - Soft-start functionality  
  - Under-voltage lockout (UVLO)  
  - Error amplifier for feedback control  

### **Descriptions and Features:**  
The UC3875DWPTR is designed for high-frequency, phase-shifted full-bridge or half-bridge power converters. It enables efficient zero-voltage switching (ZVS) to minimize switching losses. The device includes a programmable oscillator, soft-start control, and error amplifier for closed-loop regulation. It is commonly used in telecom, industrial, and computing power supplies.  

Key features include:  
- **Phase-Shifted PWM Control:** Enables efficient power conversion with reduced switching losses.  
- **Zero-Voltage Switching (ZVS):** Enhances efficiency by minimizing turn-on losses.  
- **Programmable Dead Time:** Allows optimization of resonant transitions.  
- **Error Amplifier:** Supports voltage-mode feedback control.  
- **Protection Features:** Under-voltage lockout (UVLO) and soft-start for safe operation.  

This device is suitable for applications requiring high-efficiency power conversion, such as DC-DC converters and resonant power supplies.  

(Note: Always refer to the official datasheet for detailed specifications.)
