Description and Introduction

1.5MHz/2.25MHz, 600mA Synchronous Step-Down Regulator with LDO Mode The LTC3448EMS8E#PBF is a synchronous buck-boost DC/DC converter manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Output Voltage Range:** Adjustable from 2.4V to 5.25V  
- **Output Current:** Up to 600mA  
- **Switching Frequency:** 1MHz (typical)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** MSOP-8  
- **Topology:** Buck-Boost  
- **Features:**  
  - Automatic transition between buck and boost modes  
  - Low quiescent current (25µA typical)  
  - Power Save Mode for improved efficiency at light loads  
  - Internal soft-start  
  - Short-circuit protection  
  - Thermal shutdown  

### **Descriptions:**  
The LTC3448 is a high-efficiency, fixed-frequency synchronous buck-boost DC/DC converter that seamlessly transitions between buck and boost modes. It is designed for battery-powered applications requiring a regulated output voltage above, below, or equal to the input voltage.  

### **Features:**  
- Seamless transition between buck and boost operation  
- High efficiency across a wide load range  
- Low quiescent current extends battery life  
- Fixed-frequency operation reduces noise  
- Small MSOP-8 package for space-constrained applications  
- Integrated power switches simplify design  

This device is commonly used in portable electronics, medical devices, and industrial applications where stable power conversion is required.
