Description and Introduction

Low voltage start-up flyback controller suitable for fixed frequency/CCM The TEA1733P is a 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:** Switched Mode Power Supply (SMPS) Controller  
- **Topology:** Flyback, Buck, or Buck-boost converter  
- **Input Voltage Range:** Typically operates with universal mains input (85VAC to 265VAC)  
- **Output Voltage:** Configurable based on external components  
- **Switching Frequency:** Adjustable, typically in the range of tens to hundreds of kHz  
- **Control Method:** Fixed Frequency PWM (Pulse Width Modulation)  
- **Protection Features:** Overvoltage Protection (OVP), Overcurrent Protection (OCP), Short-Circuit Protection (SCP), Over-Temperature Protection (OTP)  
- **Package:** DIP-8 (Dual In-line Package, 8 pins)  

### **Descriptions:**  
The TEA1733P is a cost-effective SMPS controller designed for low to medium power applications. It is commonly used in power adapters, LED drivers, and auxiliary power supplies. The IC integrates multiple protection features to ensure safe operation under various conditions.  

### **Features:**  
- **High Efficiency:** Optimized for energy-efficient power conversion.  
- **Low Standby Power:** Supports green-mode operation for reduced power consumption in standby mode.  
- **Soft Start:** Minimizes inrush current during startup.  
- **Cycle-by-Cycle Current Limiting:** Protects against overloads.  
- **Frequency Jittering:** Reduces EMI (Electromagnetic Interference).  
- **Wide Operating Temperature Range:** Suitable for industrial and consumer applications.  

For exact electrical characteristics, refer to the official NXP datasheet for the TEA1733P.
