Description and Introduction

Micropower Step-Down Switching Regulators in ThinSOT The LT1934IS6 is a step-up DC/DC converter manufactured by Linear Technology (now part of Analog Devices). Below are its specifications, descriptions, and features:

### **Specifications:**  
- **Manufacturer:** LT (Linear Technology)  
- **Part Number:** LT1934IS6  
- **Package:** SOT-23-6  
- **Input Voltage Range:** 1.2V to 16V  
- **Output Voltage:** Adjustable up to 34V  
- **Switching Frequency:** 1.2MHz  
- **Output Current:** Up to 400mA (depending on input/output conditions)  
- **Efficiency:** Up to 85%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Shutdown Current:** <1µA  

### **Descriptions:**  
The LT1934IS6 is a high-efficiency, fixed-frequency step-up DC/DC converter designed for battery-powered applications. It uses a current-mode architecture for fast transient response and stable operation. The device includes an internal NPN switch capable of delivering up to 400mA of output current.  

### **Features:**  
- **Wide Input Voltage Range:** 1.2V to 16V  
- **Adjustable Output Voltage (up to 34V)**  
- **1.2MHz Switching Frequency** (allows small external components)  
- **Low Shutdown Current (<1µA)**  
- **Internal Soft-Start** (reduces inrush current)  
- **Current-Mode Control** (improves stability and transient response)  
- **Small 6-Pin SOT-23 Package** (suitable for space-constrained applications)  
- **Internal NPN Power Switch** (simplifies design)  

This information is based on the manufacturer's datasheet. For detailed application-specific performance, refer to the official documentation.
