Description and Introduction

HV start-up flyback controller for DCM or QR mode; 125 kHz f_osc(h); standby output signal The TEA1552T is a power supply controller IC manufactured by NXP Semiconductors. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** NXP Semiconductors  
- **Type:** SMPS (Switched-Mode Power Supply) Controller  
- **Topology:** Flyback converter  
- **Input Voltage Range:** 70V to 276V AC (universal mains)  
- **Switching Frequency:** Adjustable, typically up to 100 kHz  
- **Output Power:** Up to 25W (depending on design)  
- **Standby Power Consumption:** <100 mW  
- **Protection Features:** Overvoltage protection (OVP), overcurrent protection (OCP), overtemperature protection (OTP), and undervoltage lockout (UVLO)  
- **Package:** SO8 (Small Outline 8-pin package)  

### **Descriptions:**
The TEA1552T is a highly integrated controller IC designed for low-power offline flyback converters. It is optimized for energy-efficient power supplies in applications such as adapters, chargers, and standby power supplies. The IC includes built-in protection mechanisms to ensure safe operation under various conditions.

### **Features:**
- **High Efficiency:** Optimized for low standby power consumption.  
- **Soft Start:** Reduces inrush current during startup.  
- **Frequency Jittering:** Reduces EMI emissions.  
- **Cycle-by-Cycle Current Limiting:** Protects against overloads.  
- **Auto-Recovery Mode:** Restarts automatically after fault conditions.  
- **Green Function:** Meets energy-saving standards (e.g., Energy Star).  

This information is based on NXP's official documentation for the TEA1552T. For detailed application notes or design guidelines, refer to the manufacturer's datasheet.
