Description and Introduction

Average Current Mode PWM Controller IC The UC2886 is a switching regulator controller IC manufactured by Texas Instruments. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Texas Instruments  
- **Type:** Switching Regulator Controller  
- **Topology:** Flyback, Forward, Boost, Buck-Boost  
- **Input Voltage Range:** 8V to 30V  
- **Switching Frequency:** Adjustable up to 1MHz  
- **Output Voltage:** Adjustable (depends on external components)  
- **Duty Cycle Range:** Up to 90%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** SOIC-16  

### **Descriptions:**
- The UC2886 is a high-performance PWM controller designed for DC-DC power supply applications.  
- It supports multiple converter topologies, including flyback, forward, boost, and buck-boost configurations.  
- The IC features adjustable frequency operation, allowing optimization for efficiency and component size.  
- It includes protection features such as undervoltage lockout (UVLO) and cycle-by-cycle current limiting.  

### **Features:**
- **Adjustable Switching Frequency:** Up to 1MHz for flexible design optimization.  
- **Wide Input Voltage Range:** Supports 8V to 30V input.  
- **High Duty Cycle Operation:** Up to 90% duty cycle for efficient power conversion.  
- **Programmable Soft-Start:** Reduces inrush current during startup.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low input voltage conditions.  
- **Cycle-by-Cycle Current Limiting:** Protects against overcurrent conditions.  
- **SOIC-16 Package:** Compact and suitable for space-constrained applications.  

This information is based solely on the manufacturer's datasheet and technical documentation.
