Description and Introduction

8-Pin Quasi Resonant Flyback Green Mode Controller 8-SOIC -40 to 105 The UCC28600DRG4 is a power management IC manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Type:** Quasi-Resonant Flyback Controller  
- **Topology:** Flyback  
- **Control Method:** Current Mode  
- **Input Voltage Range:** 85 VAC to 265 VAC (universal input)  
- **Output Voltage:** Configurable (depends on external components)  
- **Switching Frequency:** Adjustable (up to 130 kHz)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOIC-8  

### **Descriptions:**  
The UCC28600DRG4 is a high-performance, quasi-resonant flyback controller designed for offline power supplies. It optimizes efficiency by operating in valley-switching mode, reducing switching losses. It includes features like line undervoltage lockout (UVLO), cycle-by-cycle current limiting, and soft-start for reliable operation.  

### **Features:**  
- **Quasi-Resonant Operation:** Reduces switching losses for improved efficiency.  
- **Valley Switching:** Minimizes turn-on losses by detecting the lowest drain voltage.  
- **Frequency Jittering:** Reduces EMI emissions.  
- **Integrated Protections:** Includes overvoltage (OVP), overload (OLP), and over-temperature (OTP) protection.  
- **Burst Mode Operation:** Enhances light-load efficiency.  
- **Low Standby Power:** Supports energy-saving applications.  

This IC is commonly used in AC/DC power adapters, LED drivers, and auxiliary power supplies.  

(Note: Always refer to the official TI datasheet for detailed specifications and application guidelines.)
