Description and Introduction

Off-Line SMPS Current Mode Controller with integrated 650V Startup Cell/Depletion CoolMOS The part **ICE3B0565JG** is manufactured by **Infineon Technologies**. Below are the specifications, descriptions, and features based on the available knowledge:

### **Specifications:**
- **Manufacturer:** Infineon Technologies  
- **Part Number:** ICE3B0565JG  
- **Category:** Power Management IC  
- **Type:** SMPS (Switched-Mode Power Supply) Controller  
- **Topology:** Flyback  
- **Input Voltage Range:** 85 V to 265 V AC  
- **Output Power:** Up to 6.5 W (typical)  
- **Switching Frequency:** 65 kHz (fixed)  
- **Current Mode Control:** Yes  
- **Protection Features:**  
  - Overload Protection (OLP)  
  - Overvoltage Protection (OVP)  
  - Over-temperature Protection (OTP)  
  - Short-Circuit Protection (SCP)  
- **Package:** DIP-7 (Through-Hole)  

### **Description:**  
The **ICE3B0565JG** is a highly integrated PWM controller IC designed for offline flyback converters in low-power applications. It operates in current-mode control, ensuring stable and efficient power conversion. The IC includes built-in protection features to enhance reliability in power supply designs.

### **Features:**  
- **High Integration:** Combines PWM controller and power MOSFET driver.  
- **Low Standby Power:** Optimized for energy-efficient operation.  
- **Fixed Frequency Operation:** 65 kHz switching frequency for reduced EMI.  
- **Soft Start:** Minimizes inrush current during startup.  
- **Auto-Restart Protection:** Recovers automatically after fault conditions.  
- **Wide Input Voltage Range:** Supports universal mains input (85 V – 265 V AC).  

This information is based on Infineon's official documentation for the **ICE3B0565JG**. For detailed application notes and design guidelines, refer to Infineon’s datasheet.
