Description and Introduction

Off-Line SMPS Current Mode Controller with integrated 650V Startup Cell/Depletion CoolMOS? and Latched off Mode The part **ICE3A1065L** is manufactured by **Infineon Technologies**. Below are its specifications, descriptions, and features based on available factual information:  

### **Specifications:**  
- **Category:** SMPS Controller IC  
- **Topology:** Flyback  
- **Input Voltage Range:** 85V to 265V AC  
- **Output Power:** Up to 15W (depending on design)  
- **Switching Frequency:** 65 kHz (fixed)  
- **Operating Temperature Range:** -40°C to +150°C  
- **Package:** DIP-8  
- **Control Method:** Current Mode PWM  

### **Descriptions:**  
The **ICE3A1065L** is a monolithic integrated circuit designed for offline switch-mode power supplies (SMPS). It is optimized for cost-effective flyback converters with low standby power consumption. The IC integrates a high-voltage startup circuit, PWM controller, and protection features.  

### **Features:**  
- **Integrated 650V CoolMOS™ Power MOSFET**  
- **Low Startup Current (< 30 µA)**  
- **Built-in Soft Start**  
- **Cycle-by-Cycle Current Limiting**  
- **Overload Protection (OLP)**  
- **Over-Temperature Protection (OTP)**  
- **Under-Voltage Lockout (UVLO)**  
- **Auto-Restart Mode for Fault Conditions**  
- **Low EMI due to Frequency Jittering**  

This information is based on Infineon's official documentation for the ICE3A1065L. For detailed application notes or design guidelines, refer to the datasheet.
