Description and Introduction

Third Generation Fixed Frequency Intergrated Power ICs for Switched Mode Power Supplies The part **ICE3A2065Z** is manufactured by **Infineon**. Below are its specifications, descriptions, and features:

### **Specifications:**
- **Type:** SMPS (Switched-Mode Power Supply) Controller IC  
- **Topology:** Flyback  
- **Input Voltage Range:** 85V AC to 265V AC  
- **Output Power:** Up to 6W (typical)  
- **Switching Frequency:** 65 kHz (fixed)  
- **Operating Temperature Range:** -40°C to +150°C  
- **Package:** DIP-7 (PDIP-7)  

### **Descriptions:**
The **ICE3A2065Z** is a low-cost, high-performance offline SMPS controller designed for flyback converters. It integrates a high-voltage startup circuit and a PWM controller, making it suitable for low-power applications such as adapters and auxiliary power supplies.  

### **Features:**
- **Integrated High-Voltage Startup Circuit** – Reduces external component count.  
- **Fixed 65 kHz Switching Frequency** – Ensures stable operation.  
- **Built-in Soft-Start** – Reduces inrush current.  
- **Cycle-by-Cycle Current Limiting** – Protects against overloads.  
- **Auto-Restart Protection** – For short-circuit and open-loop conditions.  
- **Low Standby Power Consumption** – Meets energy efficiency standards.  
- **Under-Voltage Lockout (UVLO)** – Ensures reliable startup.  

This information is based on Infineon's official documentation for the **ICE3A2065Z**.
