Description and Introduction

Synchronous rectification with inhibit, 1.5 A, 1.5 MHz adjustable, step-down switching regulator The ST1S06APUR is a step-down DC-DC converter manufactured by STMicroelectronics. Below are the key specifications, descriptions, and features from Ic-phoenix technical data files:

### **Manufacturer:**  
STMicroelectronics  

### **Specifications:**  
- **Input Voltage Range:** 2.7V to 6V  
- **Output Voltage Range:** Adjustable from 0.8V to 5V  
- **Output Current:** Up to 1.5A  
- **Switching Frequency:** 1.5MHz (typical)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT23-5L  

### **Descriptions:**  
The ST1S06APUR is a synchronous step-down DC-DC converter designed for high efficiency and compact power supply solutions. It integrates low RDS(on) power MOSFETs and operates at a high switching frequency, enabling the use of small external components.  

### **Features:**  
- **High Efficiency:** Up to 95%  
- **Integrated Power MOSFETs:** Reduces external component count  
- **Fixed 1.5MHz Switching Frequency:** Allows for small inductors and capacitors  
- **Adjustable Output Voltage:** Via external resistors  
- **Over-Temperature Protection:** Prevents damage from excessive heat  
- **Short-Circuit Protection:** Enhances system reliability  
- **Low Dropout Operation:** Maintains regulation even when input voltage is close to output  
- **100% Duty Cycle Capability:** Supports low dropout conditions  

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