Description and Introduction

High Voltage Step-Up/Step-Down DC/DC Converter The LT3433IFE is a high voltage, high efficiency switching regulator manufactured by Linear Technology (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Input Voltage Range:** 3.5V to 60V  
- **Output Voltage Range:** Adjustable from 1.24V to 57V  
- **Output Current:** Up to 3A  
- **Switching Frequency:** 200kHz  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 16-Lead TSSOP (Exposed Pad)  
- **Topology:** Buck (Step-Down) Converter  

### **Descriptions:**
- The LT3433IFE is a monolithic, high voltage step-down switching regulator designed for high efficiency and compact designs.  
- It features a built-in NPN power switch and can handle input voltages up to 60V.  
- The regulator includes frequency compensation, soft-start, and thermal shutdown for robust operation.  

### **Features:**
- **Wide Input Voltage Range (3.5V to 60V)** – Suitable for automotive, industrial, and battery-powered applications.  
- **High Efficiency (Up to 90%)** – Minimizes power loss and heat dissipation.  
- **Adjustable Output Voltage (1.24V to 57V)** – Provides flexibility for various applications.  
- **3A Output Current Capability** – Supports high-power loads.  
- **200kHz Switching Frequency** – Balances efficiency and component size.  
- **Thermal Shutdown & Current Limit Protection** – Enhances reliability.  
- **Low Dropout Operation** – Maintains regulation even when input voltage is close to output.  
- **TSSOP-16 Package with Exposed Pad** – Improves thermal performance.
