Description and Introduction

Phase Shift Resonant Controller The UC2875N is a high-performance PWM controller manufactured by UNITRODE. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** UNITRODE  
- **Type:** PWM Controller  
- **Topology:** Supports push-pull, half-bridge, and full-bridge configurations  
- **Operating Frequency:** Up to 1 MHz  
- **Output Drive:** Dual 2A peak current totem-pole outputs  
- **Input Voltage Range:** 15V to 20V (recommended for VCC)  
- **Duty Cycle Range:** Adjustable, typically 0% to 100%  
- **Error Amplifier Bandwidth:** 10 MHz  
- **Soft-Start Capability:** Programmable  
- **Protection Features:**  
  - Under-voltage lockout (UVLO)  
  - Over-current protection  
  - Programmable dead-time control  

### **Descriptions:**
The UC2875N is designed for high-frequency switching power supply applications, providing precise PWM control for efficient power conversion. It is well-suited for telecom, industrial, and computing power supplies due to its high-speed switching capability and robust protection features.

### **Features:**
- **High-Speed Operation:** Optimized for high-frequency switching (up to 1 MHz).  
- **Dual Outputs:** Two 2A peak current outputs for driving power MOSFETs or IGBTs.  
- **Programmable Dead-Time:** Ensures safe switching transitions.  
- **Wide Input Voltage Range:** Supports flexible power supply designs.  
- **Integrated Error Amplifier:** Enhances feedback loop stability.  
- **Soft-Start Function:** Reduces inrush current during startup.  
- **Robust Protection:** Includes UVLO and over-current safeguards.
