Description and Introduction

SWITCHED-CAPACITOR VOLTAGE CONVERTERS WITH REGULATORS The LT1054C is a switched-capacitor voltage converter manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Input Voltage Range:** 3.5V to 15V  
- **Output Voltage Options:** -Vin (Inverting) or 2x Vin (Doubling)  
- **Output Current:** Up to 100mA  
- **Switching Frequency:** ~25kHz  
- **Low Quiescent Current:** 2.5mA (Typical)  
- **Efficiency:** Up to 85%  
- **Operating Temperature Range:** 0°C to 70°C  
- **Package Options:** 8-Pin PDIP, SOIC  

### **Descriptions & Features:**  
- The LT1054C is a monolithic, bipolar switched-capacitor voltage converter.  
- It can generate negative or doubled output voltages from a single positive supply.  
- Includes an onboard regulator for stable output.  
- Low power loss and high efficiency compared to traditional charge pumps.  
- Requires minimal external components (only capacitors).  
- Suitable for applications like power supply inversion, voltage doubling, and portable devices.  

This information is based on the LT1054C datasheet from Texas Instruments.
