Description and Introduction

Inductor Built-in Step-Down micro DC/DC Converters The part **XCL206C333AR-G** is a **DC/DC converter** from **Torex Semiconductor**. Below are the manufacturer's specifications, descriptions, and features:

### **Manufacturer Specifications:**
- **Input Voltage Range:** 2.0V to 6.0V  
- **Output Voltage:** 3.3V (Fixed)  
- **Output Current:** 600mA (Max)  
- **Switching Frequency:** 1.2MHz (Typical)  
- **Efficiency:** Up to 92%  
- **Quiescent Current:** 30μA (Typical)  
- **Shutdown Current:** 0.1μA (Max)  
- **Operating Temperature Range:** -40°C to +105°C  
- **Package:** SOT-25 (5-pin)  

### **Description:**
The **XCL206C333AR-G** is a **step-up (boost) DC/DC converter** with a built-in **0.5Ω NMOS switch**. It is designed for low-power applications requiring a stable 3.3V output from a wide input voltage range (2.0V to 6.0V). The device operates at a high switching frequency (1.2MHz), allowing the use of small external components. It features **automatic pulse frequency modulation (PFM) mode** for improved efficiency at light loads.

### **Key Features:**
- **High Efficiency (Up to 92%)**  
- **Low Quiescent Current (30μA Typical)**  
- **Ultra-Low Shutdown Current (0.1μA Max)**  
- **Built-in 0.5Ω NMOS Switch**  
- **Automatic PFM Mode for Light Load Efficiency**  
- **Compact SOT-25 Package**  
- **Overcurrent Protection (OCP) and Thermal Shutdown (TSD)**  
- **Stable with Ceramic Capacitors**  

This part is commonly used in **battery-powered devices, IoT applications, portable electronics, and energy-harvesting systems**.
