Description and Introduction

1.2MHz Boost DC/DC Converter with 1.5A Switch and Soft-Start The LT1946EMS8#PBF is a switching regulator IC manufactured by Linear Technology (now part of Analog Devices). Below are its key specifications, descriptions, and features based on factual data:

### **Specifications:**  
- **Manufacturer:** LINEAR (Linear Technology)  
- **Package:** MSOP-8  
- **Type:** Switching Regulator  
- **Topology:** Step-Up (Boost), Step-Down (Buck), Inverting  
- **Input Voltage Range:** 2.5V to 16V  
- **Output Voltage Range:** Adjustable  
- **Output Current:** Up to 1.2A (Switch Current Limit)  
- **Switching Frequency:** 1.2MHz (Fixed)  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +125°C  

### **Descriptions:**  
The LT1946EMS8#PBF is a high-efficiency, monolithic switching regulator that can operate in boost, buck, or inverting configurations. It integrates a 1.2A power switch and is designed for compact, battery-powered applications. Its fixed-frequency PWM operation ensures low noise and stable performance.
