Description and Introduction

Phase Shift Resonant Controller The UC2875DWPTR is a high-performance PWM controller manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Topology:** Push-Pull, Half-Bridge, Full-Bridge  
- **Control Method:** Voltage Mode  
- **Frequency Range:** Up to 1MHz  
- **Operating Voltage (VCC):** 8V to 20V  
- **Output Current (Source/Sink):** 500mA / 1A  
- **Duty Cycle Range:** 0% to 100%  
- **Switching Frequency:** Adjustable via external components  
- **Package:** SOIC-16 (DW)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The UC2875DWPTR is a pulse-width modulation (PWM) controller designed for high-frequency power supply applications. It provides precise control for push-pull, half-bridge, and full-bridge converters. The device includes features such as soft-start, undervoltage lockout (UVLO), and programmable dead-time control.  

### **Features:**  
- **High-Frequency Operation:** Supports switching frequencies up to 1MHz.  
- **Adjustable Dead Time:** Prevents shoot-through in bridge configurations.  
- **Soft-Start Function:** Reduces inrush current during startup.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation within voltage limits.  
- **Error Amplifier:** Provides closed-loop feedback control.  
- **Synchronization Capability:** Allows external clock synchronization.  
- **Thermal Shutdown Protection:** Prevents overheating.  

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