Description and Introduction

STARplug The **TEA1522T** is a power supply controller IC manufactured by **NXP Semiconductors**. Below are its key specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Input Voltage Range:** 90V to 276V AC (universal mains)  
- **Switching Frequency:** Adjustable (typically 100 kHz)  
- **Output Power:** Up to 10W (depends on design)  
- **Operating Mode:** Fixed-frequency PWM (Pulse Width Modulation)  
- **Start-up Current:** Low (typically 50 µA)  
- **Standby Power Consumption:** <100 mW  
- **Protection Features:**  
  - Overvoltage protection (OVP)  
  - Overcurrent protection (OCP)  
  - Short-circuit protection (SCP)  
  - Thermal shutdown  

### **Description:**  
The **TEA1522T** is a low-cost, energy-efficient SMPS (Switched-Mode Power Supply) controller designed for flyback converters. It integrates essential functions for power conversion, including a high-voltage startup circuit, oscillator, PWM control, and protection mechanisms. It is commonly used in adapters, chargers, and auxiliary power supplies.  

### **Features:**  
- **Integrated High-Voltage Startup Circuit** – Reduces external component count.  
- **Fixed-Frequency Operation** – Ensures stable switching performance.  
- **Soft Start** – Prevents inrush current at startup.  
- **Cycle-by-Cycle Current Limiting** – Enhances reliability.  
- **Low Standby Power Consumption** – Suitable for energy-efficient designs.  
- **DIP-8 Package** – Easy to integrate into PCB designs.  

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

Application Scenarios & Design Considerations

STARplug

Alternative Part Number

  • VIPer12A --: Integrated offline SMPS switcher with comparable power range and similar application, widely used as a direct substitute in low-power AC-DC supplies.
  • NCP1014 --: Self-supplied monolithic switching regulator for offline converters, functionally similar to the TEA1522T in low-power standby and adapter designs.
  • LNK304 --: LinkSwitch-TN family buck/offline switcher offering comparable low-power conversion capability and a common alternative in similar power supply circuits.
  • LNK304PN --: LinkSwitch-TN offline switcher offering similar low-power buck/offline conversion capability and a common drop-in alternative for small power supplies.
  • NCP1014AP065G --: Self-supplied monolithic offline switching regulator with comparable voltage/current class, suitable as an alternative in low-power flyback designs.
