Description and Introduction

Off-Line SMPS Quasi-Resonant PWM Controller with integrated 650V Startup Cell/Depletion CoolMOS In DIP-8 The part **ICE2QR4765** is manufactured by **Infineon Technologies**. Below are the specifications, descriptions, and features based on available data:  

### **Specifications:**  
- **Type:** SMPS (Switched-Mode Power Supply) Controller IC  
- **Topology:** Quasi-Resonant (QR) Flyback  
- **Input Voltage Range:** 85V to 265V AC  
- **Output Power:** Up to 65W (depending on design)  
- **Switching Frequency:** Adjustable, up to several hundred kHz  
- **Operating Temperature Range:** -40°C to +150°C  
- **Package:** DIP-7 or similar  

### **Descriptions:**  
The **ICE2QR4765** is a high-performance PWM controller designed for quasi-resonant flyback converters. It optimizes efficiency by reducing switching losses through valley switching and frequency modulation. It is commonly used in power supplies for consumer electronics, adapters, and LED drivers.  

### **Features:**  
- **Quasi-Resonant Operation:** Minimizes switching losses for higher efficiency.  
- **Frequency Jittering:** Reduces EMI noise.  
- **Built-in Protections:** Includes over-voltage (OVP), over-current (OCP), over-temperature (OTP), and brown-out protection.  
- **Soft Start:** Prevents inrush current at startup.  
- **Low Standby Power Consumption:** Meets energy efficiency standards.
