Description and Introduction

Third Generation Fixed Frequency Intergrated Power ICs for Switched Mode Power Supplies The ICE3A3065P is a power management IC manufactured by Infineon Technologies. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:  

### **Specifications:**  
- **Manufacturer:** Infineon Technologies  
- **Part Number:** ICE3A3065P  
- **Category:** Power Management IC  
- **Topology:** Flyback Converter  
- **Input Voltage Range:** 85V to 265V AC  
- **Output Power:** Up to 65W  
- **Switching Frequency:** 65 kHz (fixed)  
- **Operating Temperature Range:** -25°C to +125°C  
- **Package:** DIP-7 (PDIP-7)  
- **Protection Features:** Overvoltage, Overload, Over-temperature, Short-circuit, and Undervoltage lockout (UVLO)  

### **Descriptions:**  
The ICE3A3065P is a highly integrated PWM controller designed for offline flyback converters. It is optimized for cost-effective power supplies with high efficiency and low standby power consumption. The IC includes built-in protections and a fixed-frequency operation for stable performance in AC/DC applications.  

### **Features:**  
- **High Integration:** Combines PWM controller and 650V MOSFET in a single package.  
- **Low Standby Power:** <100mW in no-load conditions.  
- **Frequency Jittering:** Reduces EMI emissions.  
- **Soft Start:** Minimizes inrush current.  
- **Auto-Restart Protection:** Recovers automatically after fault conditions.  
- **Green Mode Operation:** Enhances efficiency at light loads.

Application Scenarios & Design Considerations

Third Generation Fixed Frequency Intergrated Power ICs for Switched Mode Power Supplies

Alternative Part Number

  • NCP1252APG --: Offline flyback PWM controller with integrated high-voltage startup, similar power range and DIP-8 package, widely used as a drop-in style replacement for ICE3A series designs.
  • UC3845BN --: Classic current-mode PWM controller in DIP-8, very common and inexpensive; requires external startup resistor but is functionally compatible for low-power flyback supplies.
  • VIPER22A --: Integrated high-voltage power switch with PWM controller in DIP-8, suitable for low-power offline SMPS and often used where ICE3A3065 was specified.
