Description and Introduction

Step-Up/Step-Down Switched Capacitor DC/DC Converters with Low-Battery Comparator The LTC1514CS8-3.3 is a low-power, step-down DC/DC converter manufactured by STMicroelectronics (ST). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Output Voltage:** 3.3V (fixed)  
- **Input Voltage Range:** 4V to 16V  
- **Output Current:** Up to 100mA  
- **Switching Frequency:** 100kHz  
- **Efficiency:** Up to 85%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SO-8  

### **Descriptions:**
The LTC1514CS8-3.3 is a micropower step-down (buck) switching regulator designed for low-power applications. It provides a fixed 3.3V output from an input voltage range of 4V to 16V, making it suitable for battery-powered and portable devices. The device operates at a switching frequency of 100kHz and includes internal power switches, reducing external component count.

### **Features:**
- Low quiescent current (typically 100µA)  
- Internal power switches (no external MOSFET required)  
- Soft-start functionality to limit inrush current  
- Short-circuit and thermal protection  
- Minimal external components required  
- Stable with low ESR ceramic capacitors  

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