Description and Introduction

600mA, 500kHz Step-Down Switching Regulator in SOT-23 The LT1933IDCB#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 40V (adjustable via external resistors)  
- **Switching Frequency:** 1.2MHz (fixed)  
- **Maximum Output Current:** 1A (dependent on input/output conditions)  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 6-Lead DFN (2mm × 2mm)  
- **Shutdown Current:** <1µA  

### **Descriptions:**
- The LT1933 is a high-efficiency, fixed-frequency step-up DC/DC converter designed for battery-powered applications.  
- It features an internal 1.5A, 40V switch, enabling high output voltages from low input sources.  
- The device operates in a current-limited, constant-frequency architecture, ensuring stable performance across varying loads.  

### **Features:**
- **Wide Input Voltage Range:** Supports operation from 1.2V to 16V.  
- **High Output Voltage Capability:** Can generate up to 40V.  
- **Low Shutdown Current:** <1µA for power-saving modes.  
- **Internal Soft-Start:** Reduces inrush current during startup.  
- **Thermal Shutdown Protection:** Prevents damage from overheating.  
- **Small Footprint:** 6-Lead DFN package for space-constrained designs.  

This information is based on the manufacturer's datasheet for the LT1933IDCB#PBF.
