Description and Introduction

TEA1623 The TEA1623PH is a Power Factor Correction (PFC) controller IC manufactured by NXP. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** NXP Semiconductors  
- **Type:** PFC Controller IC  
- **Package:** DIP-8 (Dual In-line Package)  
- **Operating Voltage Range:** 8.5V to 38V  
- **Switching Frequency:** Adjustable up to 250 kHz  
- **Maximum Duty Cycle:** 95%  
- **Standby Power Consumption:** < 100 mW  
- **Protection Features:** Overvoltage, Undervoltage, Overcurrent, and Over-temperature protection  

### **Descriptions:**  
The TEA1623PH is designed for efficient power factor correction in switch-mode power supplies (SMPS). It operates in transition mode (boundary conduction mode) to improve efficiency and reduce EMI. The IC is suitable for applications like LED drivers, adapters, and industrial power supplies.  

### **Features:**  
- **High Efficiency:** Transition mode operation for reduced switching losses.  
- **Low Standby Power:** Supports energy-saving modes.  
- **Integrated Protections:** Includes OVP, UVP, OCP, and thermal shutdown.  
- **Adjustable Frequency:** Allows optimization for different applications.  
- **Soft Start:** Reduces inrush current during startup.  
- **Low External Component Count:** Simplifies design and reduces BOM cost.  

This information is based solely on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

TEA1623

Alternative Part Number

  • NCP1200P60 --: Offline PWM current-mode controller in DIP-8 with comparable power range, widely used as a drop-in style replacement for small flyback supplies.
  • UC3842AN --: Industry-standard current-mode PWM controller in DIP-8, easy to source and well documented for low-power SMPS designs.
  • VIPER22A --: Integrated high-voltage switcher with built-in MOSFET, suitable for low-power offline flyback applications similar to the original controller.
  • LNK304PN --: LinkSwitch-TN offline switcher IC in DIP-8, a common drop-in class replacement for low-power non-isolated buck supplies.
  • NCP1014AP065G --: Self-supplied monolithic switching regulator with integrated MOSFET, suitable as an alternative for small offline power designs.
