Description and Introduction

Step-Up/Step-Down Switched Capacitor DC/DC Converters with Low-Battery Comparator The LTC1514IS8-5#PBF is a low-power, fixed 5V output charge pump DC/DC converter manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Input Voltage Range:** 2V to 5.5V  
- **Fixed Output Voltage:** 5V (±4%)  
- **Output Current:** Up to 20mA  
- **Switching Frequency:** 150kHz  
- **Low Quiescent Current:** 40µA (typical)  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-Lead SOIC  

### **Descriptions:**  
- The LTC1514IS8-5#PBF is a compact, switched-capacitor voltage doubler that generates a regulated 5V output from an input as low as 2V.  
- It requires only two external capacitors (flying and output) for operation.  
- The device features automatic shutdown when the input voltage exceeds the output voltage, preventing reverse current flow.  

### **Features:**  
- No inductors required  
- Low noise operation  
- Low dropout operation (input can be slightly below 5V)  
- Thermal shutdown protection  
- Short-circuit protected  
- Space-saving 8-pin SOIC package  

This device is commonly used in battery-powered applications, portable instruments, and low-power systems requiring a regulated 5V supply.
