Description and Introduction

White LED Step-Up Converter in SC70 and ThinSOT The LT1937ES5#TR is a 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:** 1.2V to 16V  
- **Output Voltage:** Adjustable up to 34V  
- **Switching Frequency:** 1.2MHz  
- **Maximum Output Current:** 1.2A (switch current limit)  
- **Efficiency:** Up to 87%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT-23-5  
- **Shutdown Current:** <1µA  

### **Descriptions:**
- The LT1937ES5#TR is a high-efficiency, fixed-frequency step-up DC/DC converter designed for battery-powered applications.  
- It features an internal 1.2A, 36V NPN switch and operates at a high switching frequency (1.2MHz), allowing the use of small external components.  
- The device includes a shutdown mode for low power consumption when not in use.  

### **Features:**
- **Wide Input Voltage Range (1.2V to 16V)** – Suitable for single-cell to multi-cell battery applications.  
- **Adjustable Output Voltage (Up to 34V)** – Set via an external resistor divider.  
- **High Switching Frequency (1.2MHz)** – Enables compact designs with small inductors and capacitors.  
- **Low Shutdown Current (<1µA)** – Extends battery life in portable applications.  
- **Internal Soft-Start** – Reduces inrush current during startup.  
- **Thermal Shutdown Protection** – Prevents damage from overheating.  

This device is commonly used in applications such as LED drivers, battery-powered systems, and portable electronics requiring high-voltage conversion.  

(Note: Always refer to the official datasheet for detailed specifications and application guidelines.)
