Description and Introduction

Third Generation Fixed Frequency Intergrated Power ICs for Switched Mode Power Supplies The part **ICE3B1065** is manufactured by **Infineon**.  

### **Specifications:**  
- **Type:** SMPS (Switched-Mode Power Supply) Controller IC  
- **Topology:** Flyback  
- **Input Voltage Range:** 85V to 265V AC  
- **Output Power:** Up to 10W (depending on design)  
- **Switching Frequency:** Fixed at 65 kHz  
- **Operating Temperature Range:** -40°C to +150°C  
- **Package:** DIP-7 (PDIP-7)  

### **Descriptions:**  
- Designed for offline power supplies in low-power applications.  
- Integrates a high-voltage startup circuit for reduced external components.  
- Features built-in protections including overvoltage (OVP), overload (OLP), and over-temperature (OTP).  
- Optimized for low standby power consumption.  

### **Features:**  
- **High-Voltage Startup:** Eliminates the need for an external startup resistor.  
- **Current-Mode Control:** Ensures stable operation and fast transient response.  
- **Frequency Jittering:** Reduces EMI emissions.  
- **Soft Start:** Minimizes inrush current.  
- **Auto-Restart Protection:** Safely recovers from fault conditions.  

This IC is commonly used in adapters, chargers, and auxiliary power supplies.

Application Scenarios & Design Considerations

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

Alternative Part Number

  • NCP1216A --: Offline PWM current-mode controller with integrated high-voltage startup, similar function to ICE3B1065 for SMPS applications.
  • TOP244YN --: Integrated offline switcher with built-in MOSFET and controller, suitable drop-in style replacement for low-power flyback designs.
  • VIPER22A --: Fixed-frequency offline converter with integrated power switch, commonly used as an alternative in small AC-DC power supplies.
  • TNY264PN --: TinySwitch-II family offline switcher with integrated MOSFET and self-powered startup, suitable for similar low-power isolated power supplies.
