Description and Introduction

Pulse Wide Modulation (PWM) control IC for fixed frequent (FF) operation mode The ICE2AS01 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  
- **Type:** SMPS (Switched-Mode Power Supply) Controller IC  
- **Topology:** Flyback converter  
- **Operating Voltage Range:** 8.5V to 21V  
- **Switching Frequency:** 100 kHz (fixed)  
- **Maximum Duty Cycle:** 72%  
- **Output Power (Typical):** Up to 15W (depends on application)  
- **Protection Features:** Overload, Overvoltage, Undervoltage lockout (UVLO), Soft-start  
- **Package:** DIP-8 or SO-8  

### **Descriptions:**  
The ICE2AS01 is a current-mode PWM controller designed for offline flyback converters. It is optimized for low-power applications, providing high efficiency and reliability. The IC integrates multiple protection mechanisms to ensure safe operation under various conditions.

### **Features:**  
- **Current-Mode Control:** Ensures stable operation with fast transient response.  
- **Built-in Protections:**  
  - Overload protection (OLP)  
  - Overvoltage protection (OVP)  
  - Undervoltage lockout (UVLO)  
- **Soft-Start Function:** Reduces inrush current during startup.  
- **Low Standby Power Consumption:** Suitable for energy-efficient designs.  
- **Fixed Switching Frequency:** 100 kHz operation for consistent performance.  
- **Internal Startup Circuit:** Simplifies external component requirements.  

This information is based on Infineon's official documentation for the ICE2AS01. For detailed application notes, refer to the datasheet.

Application Scenarios & Design Considerations

Pulse Wide Modulation (PWM) control IC for fixed frequent (FF) operation mode

Alternative Part Number

  • NCP1216A --: Current-mode PWM controller with integrated high-voltage startup, functionally similar to ICE2AS01 for offline SMPS applications.
  • UC3842 --: Industry-standard current-mode PWM controller widely used as a replacement in flyback converters; requires external startup resistor but is well documented.
  • SG6848 --: Green-mode PWM controller with built-in high-voltage startup circuit, suitable drop-in style alternative for low-power offline adapters.
