Description and Introduction

Constant Frequency Current Mode Step-Up DC/DC Controller in ThinSOT The LTC1872BES6#TR is a high-efficiency, monolithic synchronous step-down switching regulator manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Input Voltage Range:** 4V to 36V  
- **Output Voltage Range:** 0.8V to 34V  
- **Maximum Output Current:** 2A  
- **Switching Frequency:** 550kHz (fixed)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23-6  
- **Topology:** Synchronous Buck (Step-Down)  
- **Features:**  
  - Low quiescent current (20µA in shutdown)  
  - Adjustable output voltage  
  - Internal soft-start  
  - Short-circuit protection  
  - Thermal shutdown  
  - Synchronizable to an external clock  

### **Descriptions and Features:**  
The LTC1872BES6#TR is designed for high-efficiency step-down DC/DC conversion, making it suitable for battery-powered and industrial applications. It integrates both high-side and low-side MOSFETs, reducing external component count. The fixed-frequency PWM operation ensures predictable noise performance, while the synchronous rectification improves efficiency.  

Key features include adjustable output voltage via an external resistor divider, low dropout operation, and protection mechanisms such as thermal shutdown and current limiting. The device is available in a compact SOT-23-6 package, making it ideal for space-constrained applications.
