Description and Introduction

1.2MHz Boost DC/DC Converter in ThinSOT with 2A Switch The LT1935ES5#PBF 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 Range:** Up to 34V (adjustable via external resistors)  
- **Output Current:** Up to 1.2A (switch current limit)  
- **Switching Frequency:** 1.2MHz (fixed)  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT-23-5 (ThinSOT)  
- **Shutdown Current:** <1µA  

### **Descriptions:**
- The LT1935ES5#PBF is a high-efficiency, fixed-frequency step-up DC/DC converter.  
- It includes an internal 1.2A, 36V power switch, making it suitable for applications requiring high output voltages from low input sources.  
- The device operates in a current-limited, pulse-width modulation (PWM) mode for stable performance.  

### **Features:**
- **Wide Input Voltage Range:** Supports operation from 1.2V to 16V.  
- **High Output Voltage Capability:** Can generate up to 34V.  
- **Internal Power Switch:** Eliminates the need for an external MOSFET.  
- **Low Shutdown Current:** Consumes <1µA when disabled.  
- **Fixed 1.2MHz Switching Frequency:** Reduces external component size.  
- **Thermal Shutdown Protection:** Prevents damage from overheating.  
- **Soft-Start Function:** Reduces inrush current during startup.  

This device is commonly used in battery-powered systems, LCD bias supplies, and other applications requiring a boost converter.  

(Note: For detailed application circuits and additional specifications, refer to the official datasheet.)
