Description and Introduction

Power IC for PWM Type Switching Power Supply with Low Noise and Low Standby Power The STR-W6253D is a switching regulator IC manufactured by Sanken (STR). Below are the specifications, descriptions, and features based on available data:

### **Specifications:**  
- **Input Voltage Range:** 85V to 265V AC  
- **Output Power:** Up to 12W (depending on design)  
- **Switching Frequency:** ~66kHz  
- **Maximum Drain-Source Voltage (VDSS):** 650V  
- **Maximum Drain Current (ID):** 1.5A  
- **Standby Power Consumption:** <100mW  
- **Operating Temperature Range:** -25°C to +85°C  
- **Package:** TO-220F (5-pin)  

### **Description:**  
The STR-W6253D is a high-voltage switching regulator IC designed for offline power supplies. It integrates a power MOSFET, PWM controller, and protection circuits into a single package. It is commonly used in AC/DC converters for low-power applications such as adapters, LED drivers, and auxiliary power supplies.

### **Features:**  
- **Built-in High-Voltage MOSFET:** Reduces external component count.  
- **PWM Control:** Fixed-frequency operation for stable performance.  
- **Protection Circuits:** Includes overcurrent protection (OCP), overvoltage protection (OVP), and thermal shutdown (TSD).  
- **Low Standby Power:** Supports energy-efficient designs.  
- **Soft-Start Function:** Reduces inrush current during startup.  
- **Frequency Jittering:** Helps minimize EMI noise.
