Description and Introduction

Micropower Step-Down Switching Regulators in ThinSOT The LT1934IS6#PBF is a step-up DC/DC converter manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Input Voltage Range:** 1.2V to 16V  
- **Output Voltage:** Adjustable up to 40V  
- **Output Current:** Up to 1.2A (switch current limit)  
- **Switching Frequency:** 1.2MHz  
- **Efficiency:** Up to 85%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23-6  

### **Descriptions:**  
The LT1934IS6#PBF is a high-efficiency, fixed-frequency step-up DC/DC converter. It is designed for applications requiring high output voltages from low input sources. The device includes an internal NPN switch and operates at a high switching frequency, allowing the use of small external components.  

### **Features:**  
- **Wide Input Voltage Range:** Operates from 1.2V to 16V.  
- **Adjustable Output Voltage:** Can be set up to 40V.  
- **High Switching Frequency:** 1.2MHz enables compact designs.  
- **Internal Switch:** Integrated 1.2A NPN power switch.  
- **Low Shutdown Current:** <1µA in shutdown mode.  
- **Thermal Protection:** Includes thermal shutdown.  
- **Soft-Start:** Reduces inrush current.  

This device is commonly used in battery-powered systems, LCD bias supplies, and other applications requiring high voltage conversion.
