Description and Introduction

Third Generation Fixed Frequency Intergrated Power ICs for Switched Mode Power Supplies The part **ICE3A2065** is manufactured by **STMicroelectronics (ST)**.  

### **Specifications:**  
- **Category:** SMPS (Switched-Mode Power Supply) Controller  
- **Topology:** Flyback  
- **Input Voltage Range:** 85 V to 265 V (AC)  
- **Output Power:** Up to 25 W (depending on design)  
- **Switching Frequency:** Fixed at 65 kHz  
- **Operating Mode:** Quasi-Resonant (QR) for improved efficiency  
- **Protection Features:**  
  - Overload Protection (OLP)  
  - Overvoltage Protection (OVP)  
  - Over-temperature Protection (OTP)  
  - Brownout Protection  
  - Auto-restart mode for fault recovery  
- **Package:** DIP-8 or SO-8  

### **Descriptions:**  
The **ICE3A2065** is a high-performance offline PWM controller designed for flyback converters in low-power applications. It integrates a high-voltage startup circuit, reducing external component count. The quasi-resonant operation helps minimize switching losses, improving efficiency.  

### **Features:**  
- Built-in high-voltage startup  
- Low standby power consumption  
- Frequency jittering for reduced EMI  
- Soft-start function for smooth power-up  
- Cycle-by-cycle current limiting  
- Green-mode operation for light-load efficiency  

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