Description and Introduction

Micropower DC/DC Converter Adjustable and Fixed 5V/ 12V The LT1108CS8-5 is a micropower DC-DC converter manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Input Voltage Range:** 1.2V to 12V  
- **Fixed Output Voltage:** 5V  
- **Output Current:** Up to 100mA  
- **Quiescent Current:** 110µA (typical)  
- **Switching Frequency:** 50kHz (typical)  
- **Efficiency:** Up to 80%  
- **Operating Temperature Range:** 0°C to 70°C  
- **Package:** SO-8  

### **Descriptions:**  
The LT1108CS8-5 is a step-up (boost) switching regulator designed for low-power applications. It integrates a power switch, oscillator, and control circuitry, requiring minimal external components. It is optimized for battery-powered systems where efficiency and compact size are critical.  

### **Features:**  
- Low quiescent current for extended battery life  
- Operates down to 1.2V input  
- Internal power switch (NPN transistor)  
- Requires only three external components (inductor, diode, and capacitor)  
- No external catch diode needed for some configurations  
- Soft-start capability to limit inrush current  

This device is commonly used in portable electronics, medical devices, and low-power sensor applications.
