Description and Introduction

Micropower High Output Current Step-Up Adjustable and Fixed 5V DC/DC Converters The LT1302 is a micropower step-up DC/DC converter manufactured by Linear Technology (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Input Voltage Range:** 1.8V to 12V  
- **Output Voltage Range:** Adjustable up to 30V  
- **Output Current:** Up to 300mA (depending on input/output conditions)  
- **Switching Frequency:** 500kHz  
- **Quiescent Current:** 100µA (typical)  
- **Shutdown Current:** <1µA  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Options:** 8-Pin PDIP, SOIC  

### **Descriptions:**
- The LT1302 is a high-efficiency, low-power step-up (boost) DC/DC converter designed for battery-powered applications.  
- It includes an internal NPN power switch (1A peak current) and requires minimal external components.  
- The device is optimized for low-input voltage operation, making it suitable for single or dual-cell battery systems.  

### **Features:**
- **Low Quiescent Current:** 100µA (typical) for extended battery life.  
- **Wide Input Range:** Operates from 1.8V to 12V.  
- **Adjustable Output Voltage:** Can be set up to 30V using an external resistor divider.  
- **Internal Power Switch:** Eliminates the need for an external MOSFET.  
- **Shutdown Mode:** Reduces current consumption to <1µA.  
- **High Efficiency:** Up to 85% (depending on conditions).  
- **Soft-Start Function:** Prevents inrush current at startup.  
- **Short-Circuit Protection:** Improves reliability.  

The LT1302 is commonly used in portable electronics, medical devices, and other applications requiring efficient power conversion from low-voltage sources.
