Description and Introduction

Lowest cost, lowest component count switcher solution The **TOP226Y** is a member of the **TOPSwitch-GX** family of integrated switch-mode power supply (SMPS) ICs, manufactured by **Power Integrations**.  

### **Key Specifications:**  
- **Input Voltage Range:** 85–265V AC (universal input)  
- **Output Power (Max):** Up to **29W** (open frame, 230V AC)  
- **Switching Frequency:** 132 kHz  
- **Integrated Features:**  
  - High-voltage **700V MOSFET**  
  - **PWM controller** with cycle-by-cycle current limiting  
  - **Auto-restart protection** for overload, short-circuit, and thermal shutdown  
  - **Frequency jittering** for reduced EMI  
  - **Soft-start** for reduced inrush current  
- **Package:** TO-220-7C (with isolated tab)  

### **Descriptions & Features:**  
- Designed for **offline power supplies** in applications like adapters, chargers, and auxiliary power.  
- Combines **PWM control, high-voltage MOSFET, and protection circuits** in a single IC.  
- **EcoSmart® technology** for high efficiency and low standby power consumption.  
- **Primary-side regulation (PSR)** eliminates the need for an optocoupler in some designs.  
- **Thermal shutdown** protects against overheating.  

For detailed datasheets, refer to **Power Integrations' official documentation**.
