Description and Introduction

100kHz, 5A, 2.5A and 1.25A High Efficiency Switching Regulators The LT1172IS8#PBF is a switching regulator IC manufactured by Linear Technology (now part of Analog Devices). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** LINEAR (Linear Technology)  
- **Part Number:** LT1172IS8#PBF  
- **Package:** SOIC-8  
- **Type:** Switching Regulator  
- **Topology:** Buck, Boost, Flyback, Inverting  
- **Input Voltage Range:** 3V to 60V  
- **Output Voltage Range:** Adjustable (depends on configuration)  
- **Output Current:** Up to 1.25A (switch current limit)  
- **Switching Frequency:** 100kHz

### **Descriptions:**  
The LT1172IS8#PBF is a versatile monolithic switching regulator that can be configured for step-down (buck), step-up (boost), flyback, or inverting applications. It includes an onboard 1.25A power switch, oscillator, and control circuitry. The device operates from a wide input voltage range, making it suitable for battery-powered and industrial applications.

### **Features:**  
- **Wide Input Voltage Range (3V to 60V)**  
- **1.25A Internal Switch Current Limit**  
- **Low Quiescent Current (6mA typical)**  
- **Adjustable Output Voltage**  
- **100kHz Switching Frequency**  
- **Thermal Shutdown Protection**  
- **Short-Circuit Protection**  
- **SOIC-8 Package for Compact Designs**  

This information is based solely on the manufacturer's datasheet and technical documentation.
