Description and Introduction

450mA, Low Noise Current Mode Step-Down DC/DC Converter The LTC1433IGN#PBF is a high-efficiency, low-noise synchronous step-down switching regulator controller 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:** 2.5V to 5V (adjustable)  
- **Switching Frequency:** 200kHz (adjustable)  
- **Maximum Duty Cycle:** 100%  
- **Quiescent Current:** 1.5mA (typical)  
- **Operating Temperature Range:** -40°C to 85°C  
- **Package:** 16-Lead SSOP  

### **Descriptions:**
The LTC1433IGN#PBF is designed for high-efficiency DC/DC conversion applications, providing precise output voltage regulation with minimal external components. It features a synchronous rectification architecture to improve efficiency and reduce power dissipation. The device is suitable for battery-powered systems, industrial applications, and telecom equipment.

### **Features:**
- **Synchronous Operation:** Reduces power loss and improves efficiency.  
- **Low Dropout Operation:** Allows 100% duty cycle for extended battery life.  
- **Adjustable Frequency:** External resistor sets switching frequency (up to 300kHz).  
- **Soft-Start:** Reduces inrush current during startup.  
- **Current Mode Control:** Ensures fast transient response and stable operation.  
- **Short-Circuit Protection:** Enhances system reliability.  
- **Low Shutdown Current:** <10µA when disabled.  

This information is strictly based on the manufacturer's datasheet.
