Description and Introduction

Single Cell High Current Micropower 600kHz Boost DC/DC Converter The LT1308 is a micropower, step-up DC/DC converter manufactured by Linear Technology (LTC). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Input Voltage Range:** 1.8V to 12V  
- **Output Voltage Range:** Adjustable up to 30V  
- **Switching Frequency:** 100kHz  
- **Quiescent Current:** 110µA (typical)  
- **Maximum Output Current:** 300mA (at 5V input)  
- **Shutdown Current:** 1µA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Options:** SO-8, PDIP-8  

### **Descriptions:**
- The LT1308 is designed for battery-powered applications requiring high efficiency and low quiescent current.  
- It includes an internal NPN power switch, simplifying external circuitry.  
- The converter operates in discontinuous mode, making it suitable for low-power applications.  

### **Features:**
- **Low Quiescent Current:** Only 110µA, ideal for battery-powered systems.  
- **Wide Input Voltage Range:** Supports operation from 1.8V to 12V.  
- **Adjustable Output Voltage:** Can be set up to 30V using external resistors.  
- **Internal Power Switch:** Eliminates the need for an external MOSFET.  
- **Shutdown Mode:** Reduces current consumption to 1µA when disabled.  
- **Compact Design:** Available in small SO-8 and PDIP-8 packages.
