Description and Introduction

Integrated Power ICs The part **ICE2B365** is manufactured by **Infineon Technologies**. Below are the specifications, descriptions, and features based on available information:

### **Specifications:**  
- **Category:** SMPS (Switched-Mode Power Supply) Controller IC  
- **Topology:** Flyback converter  
- **Operating Voltage Range:** 8.5V to 21V (VCC)  
- **Switching Frequency:** Fixed frequency (typically around 100 kHz)  
- **Maximum Duty Cycle:** ~72%  
- **Output Power:** Up to several tens of watts (application-dependent)  
- **Protection Features:**  
  - Overload protection (OLP)  
  - Overvoltage protection (OVP)  
  - Undervoltage lockout (UVLO)  
  - Soft-start function  
- **Package:** Typically available in **DIP-8** or **SOIC-8**  

### **Description:**  
The **ICE2B365** is a current-mode PWM controller designed for offline flyback converters in power supply applications. It integrates critical functions such as startup circuitry, oscillator, error amplifier, and protection mechanisms to simplify design and improve reliability.  

### **Features:**  
- **Current-Mode Control:** Ensures stable operation and fast transient response.  
- **Low Startup Current:** Reduces power dissipation during startup.  
- **Built-in Protections:** Enhances system reliability with OVP, OLP, and thermal shutdown.  
- **Soft-Start:** Minimizes inrush current during power-up.  
- **Frequency Jittering:** Reduces EMI emissions for compliance with regulatory standards.  

This IC is commonly used in AC/DC adapters, LED drivers, and auxiliary power supplies. For exact application details, refer to Infineon’s official datasheet.

Application Scenarios & Design Considerations

Integrated Power ICs

Alternative Part Number

  • NCP1252ADR2G --: Current-mode PWM controller in a similar power range, commonly used as a drop-in replacement for offline flyback designs; different series name makes it easy to distinguish.
  • UC3845BN --: Industry-standard current-mode PWM controller with comparable drive and protection features, widely available and well documented as an alternative to ICE2B365.
  • SG6848DZ --: Green-mode PWM controller for offline SMPS with similar functionality and package options, suitable as a functional substitute.
