Description and Introduction

Constant Frequency Current Mode Step-Down DC/DC Controller in SOT-23 The LTC1772ES6#PBF 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 VIN  
- **Maximum Output Current:** 1.5A  
- **Switching Frequency:** 200kHz to 2MHz (adjustable with external resistor)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to 125°C  
- **Package:** SOT-23-6  
- **Features:**  
  - Synchronous rectification for high efficiency  
  - Adjustable switching frequency  
  - Low dropout operation (100% duty cycle)  
  - Internal soft-start  
  - Current mode control for fast transient response  
  - Short-circuit protection  
  - Low quiescent current (40μA in shutdown)  

### **Descriptions:**  
The LTC1772ES6#PBF is a compact, high-performance step-down DC/DC converter designed for applications requiring high efficiency and a wide input voltage range. It integrates both the main and synchronous power switches, reducing external component count.  

### **Features:**  
- **Wide Input Voltage Range:** Supports 4V to 36V input.  
- **High Efficiency:** Uses synchronous rectification to minimize power loss.  
- **Adjustable Frequency:** Allows optimization for efficiency or component size.  
- **Low Dropout Operation:** Maintains regulation even when input voltage approaches output voltage.  
- **Protection Features:** Includes overcurrent and thermal shutdown protection.  
- **Compact Design:** SOT-23-6 package for space-constrained applications.  

This regulator is suitable for battery-powered systems, industrial applications, and automotive power supplies.
