### **Descriptions:**
The **KA5L0165R** is a **PWM (Pulse Width Modulation) controller** designed for **offline switch-mode power supplies (SMPS)**. It integrates a **high-voltage MOSFET** and control circuitry, making it suitable for **low-power AC/DC converters** such as adapters, chargers, and auxiliary power supplies.
### **Features:**
- **Built-in 650V MOSFET** for simplified design.
- **Low standby power consumption** for energy-efficient applications.
- **Fixed 100 kHz switching frequency** for stable operation.
- **Auto-restart protection** for overload and short-circuit conditions.
- **Internal soft-start** to reduce inrush current.
- **Cycle-by-cycle current limiting** for improved reliability.
- **Thermal shutdown** for overtemperature protection.
