Description and Introduction

Third Generation Fixed Frequency Intergrated Power ICs for Switched Mode Power Supplies The part **ICE3B1565** is an integrated circuit (IC) manufactured by **Infineon Technologies**. Below are its key specifications, descriptions, and features based on available technical documentation:  

### **Manufacturer:**  
- **Infineon Technologies**  

### **Description:**  
- The **ICE3B1565** is a **PWM controller IC** designed for **offline switched-mode power supplies (SMPS)**.  
- It is part of the **CoolSET™** family, optimized for **low-power applications** with high efficiency.  
- It integrates a **high-voltage startup circuit**, reducing external component count.  

### **Key Features:**  
1. **Voltage Range:**  
   - **Input Voltage (VIN):** Up to **650V** (for high-voltage applications).  
   - **Operating Voltage (VCC):** Typically **8.5V to 21V**.  

2. **Switching Frequency:**  
   - **Fixed frequency operation** (typically **65 kHz**).  

3. **Current Mode Control:**  
   - **Peak current mode control** for improved transient response.  

4. **Protection Features:**  
   - **Overvoltage protection (OVP)**  
   - **Overcurrent protection (OCP)**  
   - **Overload protection (OLP)**  
   - **Undervoltage lockout (UVLO)**  

5. **Efficiency Enhancements:**  
   - **Burst mode operation** for low standby power consumption.  
   - **Soft-start function** to reduce inrush current.  

6. **Package:**  
   - **DIP-8 (PDIP-8)** or **SO-8 (SOIC-8)** package options.  

### **Applications:**  
- **AC/DC power supplies** (e.g., adapters, chargers).  
- **Auxiliary power supplies** for industrial and consumer electronics.  
- **LED drivers** and **low-power SMPS designs**.  

For detailed electrical characteristics and application circuits, refer to the official **Infineon ICE3B1565 datasheet**.
