Description and Introduction

Off-Line SMPS Current Mode Controller with integrated 650V Here are the factual details about the **ICE3BR1765JZ** from the manufacturer **Infineon**:

### **Specifications:**
- **Manufacturer:** Infineon Technologies  
- **Category:** Power Management ICs  
- **Type:** SMPS Controller (Switched-Mode Power Supply)  
- **Topology:** Quasi-Resonant (QR) Flyback  
- **Input Voltage Range:** 85 V to 265 V (AC)  
- **Output Power:** Up to 25 W (depending on design)  
- **Switching Frequency:** Adjustable, up to 130 kHz  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** DIP-7 (Through-Hole)  
- **Protection Features:** Overvoltage (OVP), Overcurrent (OCP), Overload (OLP), Short-Circuit (SCP), and Thermal Shutdown  

### **Descriptions:**
The **ICE3BR1765JZ** is a high-performance offline SMPS controller designed for low-power applications. It operates in quasi-resonant mode for improved efficiency and reduced EMI. It is commonly used in AC/DC power supplies for consumer electronics, adapters, and auxiliary power supplies.

### **Features:**
- **Quasi-Resonant Operation:** Enhances efficiency by reducing switching losses.  
- **Low Standby Power:** Meets energy-saving standards (e.g., ENERGY STAR).  
- **Integrated Protections:** Built-in safeguards for reliable operation.  
- **Frequency Jittering:** Reduces EMI emissions for compliance with standards.  
- **Soft Start:** Minimizes inrush current during startup.  
- **Auto-Restart Mode:** Recovers automatically after fault conditions.
