Description and Introduction

Micropower Buck Regulator with Integrated Boost and Catch Diodes The LT3470ETS8 is a step-down switching regulator manufactured by Linear Technology (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 4V to 36V  
- **Output Voltage Range:** Adjustable from 1.24V to 35V  
- **Output Current:** Up to 1.1A  
- **Switching Frequency:** 1MHz (fixed)  
- **Efficiency:** Up to 90%  
- **Quiescent Current:** 20µA (in shutdown mode)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** TSOT-8 (Thin Small Outline Transistor)  

### **Descriptions:**  
- The LT3470ETS8 is a **monolithic buck (step-down) DC/DC converter** with an internal **1.5A, 40V switch**.  
- It is designed for **battery-powered applications**, providing high efficiency and compact power solutions.  
- The regulator operates in **current-mode control**, ensuring stable performance with fast transient response.  
- It includes **soft-start functionality** to limit inrush current during startup.  

### **Features:**  
- **Wide Input Voltage Range (4V to 36V)** – Suitable for automotive and industrial applications.  
- **Low Dropout Operation** – Maintains regulation even when the input voltage is close to the output.  
- **Adjustable Output Voltage** – Set via an external resistor divider.  
- **1MHz Switching Frequency** – Allows the use of small external components.  
- **Thermal Shutdown & Current Limit Protection** – Enhances reliability.  
- **Small TSOT-8 Package** – Space-saving for compact designs.  

This regulator is commonly used in **portable devices, automotive systems, and industrial power supplies**.
