Description and Introduction

Backup Battery Controller with Fixed Output The LTC1559CS8-3.3 is a low-power, high-efficiency step-up DC/DC converter manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Input Voltage Range:** 0.8V to 5.5V  
- **Output Voltage:** 3.3V (fixed)  
- **Output Current:** Up to 100mA  
- **Switching Frequency:** 300kHz  
- **Efficiency:** Up to 90%  
- **Quiescent Current:** 12µA (typical)  
- **Package:** 8-Lead SOIC  
- **Operating Temperature Range:** -40°C to +85°C  
- **Shutdown Current:** <1µA  

### **Descriptions and Features:**  
- Designed for battery-powered applications requiring a regulated 3.3V output.  
- Uses a single-cell or dual-cell alkaline/NiMH battery input.  
- Low start-up voltage (0.8V) enables operation from nearly depleted batteries.  
- Internal soft-start reduces inrush current.  
- Automatic Burst Mode® operation improves efficiency at light loads.  
- Compact, thermally efficient SOIC-8 package.  
- No external Schottky diode required (internal synchronous rectifier).  

This converter is ideal for portable devices, wireless sensors, and other low-power applications.
